Gray lay awake until after dawn. Vivid images of the evening's
entertainment kept returning to him, and he found them difficult
to banish. The Extra Sarah had chosen - C7, one of the twenty-four-year-olds
- had been muzzled and tightly bound throughout, but it had made
copious noises in its throat, and its eyes had been remarkably
expressive. Gray had learnt, years ago, to keep a mask of mild
amusement and boredom on his face, whatever he was feeling; to
see fear, confusion, distress and ecstasy, nakedly displayed on
features that, in spite of everything, were unmistakably his own,
had been rather like a nightmare of losing control.
Of course, it had also been as inconsequential as a nightmare;
he had not lost control for a moment, however much his
animal look-alike had rolled its eyes, and moaned, and trembled.
His appetite for sexual novelty aside, perhaps he had agreed
to Sarah's request for that very reason: to see this primitive
aspect of himself unleashed, without the least risk to his own
equilibrium.
He decided to have the creature put down in the morning; he didn't
want it corrupting its clone-brothers, and he couldn't be bothered
arranging to have it kept in isolation. Extras had their sex
drives substantially lowered by drugs, but not completely eliminated
- that would have had too many physiological side-effects - and
Gray had heard that it took just one clone who had discovered
the possibilities, to trigger widespread masturbation and homosexual
behaviour throughout the batch. Most owners would not have cared,
but Gray wanted his Extras to be more than merely healthy; he
wanted them to be innocent, he wanted them to be without
sin. He was not a religious man, but he could still appreciate
the emotional power of such concepts. When the time came for
his brain to be moved into a younger body, he wanted to begin
his new life with a sense of purification, a sense of rebirth.
However sophisticated his amorality, Gray freely admitted that
at a certain level, inaccessible to reason, his indulgent life
sickened him, as surely as it sickened his body. His family and
his peers had always, unequivocally, encouraged him to seek pleasure,
but perhaps he had been influenced - subconsciously and unwillingly
- by ideas which still prevailed in other social strata. Since
the late twentieth century, when - in affluent countries - cardiovascular
disease and other "diseases of lifestyle" had become
the major causes of death, the notion that health was a reward
for virtue had acquired a level of acceptance unknown since the
medieval plagues. A healthy lifestyle was not just pragmatic,
it was righteous. A heart attack or a stroke, lung cancer
or liver disease - not to mention AIDS - was clearly a punishment
for some vice that the sufferer had chosen to pursue. Twenty-first
century medicine had gradually weakened many of the causal links
between lifestyle and life expectancy - and the advent of Extras
would, for the very rich, soon sever them completely - but the
outdated moral overtones persisted nonetheless.
In any case, however fervently Gray approved of his gluttonous,
sedentary, drug-hazed, promiscuous life, a part of him felt guilty
and unclean. He could not wipe out his past, nor did he wish
to, but to discard his ravaged body and begin again in blameless
flesh would be the perfect way to neutralise this irrational self-disgust.
He would attend his own cremation, and watch his "sinful"
corpse consigned to "hellfire"! Atheists, he decided,
are not immune to religious metaphors; he had no doubt that the
experience would be powerfully moving, liberating beyond belief.
Three months later, Sarah Brash's lawyers informed him that she
had conceived a child (which, naturally, she'd had transferred
to an Extra surrogate), and that she cordially requested that
Gray provide her with fifteen billion dollars to assist with the
child's upbringing.
His first reaction was a mixture of irritation and amusement at
his own naivety. He should have suspected that there'd been more
to Sarah's request than sheer perversity. Her wealth was comparable
to his own, but the prospect of living for centuries seemed to
have made the rich greedier than ever; a fortune that sufficed
for seven or eight decades was no longer enough.
On principle, Gray instructed his lawyers to take the matter to
court - and then he began trying to ascertain what his chances
were of winning. He'd had a vasectomy years ago, and could produce
records proving his infertility, at least on every occasion he'd
had a sperm count measured. He couldn't prove that he
hadn't had the operation temporarily reversed, since that could
now be done with hardly a trace, but he knew perfectly well that
the Extra was the father of the child, and he could prove that.
Although the Extras' brain damage resulted solely from foetal
microsurgery, rather than genetic alteration, all Extras were
genetically tagged with a coded serial number, written into portions
of DNA which had no active function, at over a thousand different
sites. What's more, these tags were always on both chromosomes
of each pair, so any child fathered by an Extra would necessarily
inherit all of them. Gray's biotechnology advisers assured him
that stripping these tags from the zygote was, in practice, virtually
impossible.
Perhaps Sarah planned to freely admit that the Extra was the father,
and hoped to set a precedent making its owner responsible for
the upkeep of its human offspring. Gray's legal experts were
substantially less reassuring than his geneticists. Gray could
prove that the Extra hadn't raped her - as she no doubt knew,
he'd taped everything that had happened that night - but that
wasn't the point; after all, consenting to intercourse would not
have deprived her of the right to an ordinary paternity suit.
As the tapes also showed, Gray had known full well what was happening,
and had clearly approved. That the late Extra had been unwilling
was, unfortunately, irrelevant.
After wasting an entire week brooding over the matter, Gray finally
gave up worrying. The case would not reach court for five or
six years, and was unlikely to be resolved in less than a decade.
He promptly had his remaining Extras vasectomised - to prove
to the courts, when the time came, that he was not irresponsible
- and then he pushed the whole business out of his mind.
Almost.
A few weeks later, he had a dream. Conscious all the while that
he was dreaming, he saw the night's events re-enacted, except
that this time it was he who was bound and muzzled, slave
to Sarah's hands and tongue, while the Extra stood back and watched.
But . . . had they merely swapped places, he wondered, or had
they swapped bodies? His dreamer's point of view told
him nothing - he saw all three bodies from the outside - but the
lean young man who watched bore Gray's own characteristic jaded
expression, and the middle-aged man in Sarah's embrace moaned
and twitched and shuddered, exactly as the Extra had done.
Gray was elated. He still knew that he was only dreaming, but
he couldn't suppress his delight at the inspired idea of keeping
his old body alive with the Extra's brain, rather than
consigning it to flames. What could be more controversial, more
outrageous, than having not just his Extras, but his own discarded
corpse, walking the grounds of his estate? He resolved at
once to do this, to abandon his long-held desire for a symbolic
cremation. His friends would be shocked into the purest admiration
- as would the fanatics, in their own way. True infamy had proved
elusive; people had talked about his last stunt for a week or
two, and then forgotten it - but the midsummer party at which
the guest of honour was Daniel Gray's old body would be remembered
for the rest of his vastly prolonged life.
Over the next few years, the medical research division of Gray's
vast corporate empire began to make significant progress on the
brain transplant problem.
Transplants between newborn Extras had been successful for decades.
With identical genes, and having just emerged from the very same
womb (or from the anatomically and biochemically indistinguishable
wombs of two clone-sister Extras), any differences between donor
and recipient were small enough to be overcome by a young, flexible
brain.
However, older Extras - even those raised identically - had shown
remarkable divergences in many neural structures, and whole-brain
transplants between them had been found to result in paralysis,
sensory dysfunction, and sometimes even death. Gray was no neuroscientist,
but he could understand roughly what the problem was: Brain and
body grow and change together throughout life, becoming increasingly
reliant on each other's idiosyncrasies, in a feed-back process
riddled with chaotic attractors - hence the unavoidable differences,
even between clones. In the body of a human (or an Extra), there
are thousands of sophisticated control systems which may include
the brain, but are certainly not contained within it, involving
everything from the spinal cord and the peripheral nervous system,
to hormonal feedback loops, the immune system, and, ultimately,
almost every organ in the body. Over time, all of these elements
adapt in some degree to the particular demands placed upon them
- and the brain grows to rely upon the specific characteristics
that these external systems acquire. A brain transplant throws
this complex interdependence into disarray - at least as badly
as a massive stroke, or an extreme somatic trauma.
Sometimes, two or three years of extensive physiotherapy could
enable the transplanted brain and body to adjust to each other
- but only between clones of equal age and indistinguishable lifestyles.
When the brain donor was a model of a likely human candidate
- an intentionally overfed, under-exercised, drug-wrecked Extra,
twenty or thirty years older than the body donor - the result
was always death or coma.
The theoretical solution, if not the detailed means of achieving
it, was obvious. Those portions of the brain responsible for
motor control, the endocrine system, the low-level processing
of sensory data, and so on, had to be retained in the body in
which they had matured. Why struggle to make the donor brain
adjust to the specifics of a new body, when that body's original
brain already contained neural systems fine-tuned to perfection
for the task? If the aim was to transplant memory and personality,
why transplant anything else?
After many years of careful brain-function mapping, and the identification
and synthesis of growth factors which could trigger mature neurons
into sending forth axons across the boundaries of a graft, Gray's
own team had been the first to try partial transplants. Gray
watched tapes of the operations, and was both repelled and amused
to see oddly shaped lumps of one Extra's brain being exchanged
with the corresponding regions of another's; repelled by visceral
instinct, but amused to see the seat of reason - even in a mere
Extra - being treated like so much vegetable matter.
The forty-seventh partial transplant, between a sedentary, ailing
fifty-year-old, and a fit, healthy twenty-year-old, was an unqualified
success. After a mere two months of recuperation, both Extras
were fully mobile, with all five senses completely unimpaired.
Had they swapped memories and "personalities"? Apparently,
yes. Both had been observed by a team of psychologists for a
year before the operation, and their behaviour extensively characterised,
and both had been trained to perform different sets of tasks for
rewards. After the selective brain swap, the learned tasks, and
the observed behavioural idiosyncrasies, were found to have followed
the transplanted tissue. Of course, eventually the younger, fitter
Extra began to be affected by its newfound health, becoming substantially
more active than it had been in its original body - and the Extra
now in the older body soon showed signs of acquiescing to its
ill-health. But regardless of any post-transplant adaption to
their new bodies, the fact remained that the Extras' identities
- such as they were - had been exchanged.
After a few dozen more Extra-Extra transplants, with virtually
identical outcomes, the time came for the first human-Extra trials.
Gray's parents had both died years before (on the operating table
- an almost inevitable outcome of their hundreds of non-essential
transplants), but they had left him a valuable legacy; thirty
years ago, their own scientists had (illegally) signed up fifty
men and women in their early twenties, and Extras had been made
for them. These volunteers had been well paid, but not so well
paid that a far larger sum, withheld until after the actual transplant,
would lose its appeal. Nobody had been coerced, and the seventeen
who'd dropped out quietly had not been punished. An eighteenth
had tried blackmail - even though she'd had no idea who was doing
the experiment, let alone who was financing it - and had died
in a tragic ferry disaster, along with three hundred and nine
other people. Gray's people believed in assassinations with a
low signal-to-noise ratio.
Of the thirty-two human-Extra transplants, twenty-nine were pronounced
completely successful. As with the Extra-Extra trials, both bodies
were soon fully functional, but now the humans in the younger
bodies could - after a month or two of speech therapy - respond
to detailed interrogation by experts, who declared that their
memories and personalities were intact.
Gray wanted to speak to the volunteers in person, but knew that
was too risky, so he contented himself with watching tapes of
the interviews. The psychologists had their barrages of supposedly
rigourous tests, but Gray preferred to listen to the less formal
segments, when the volunteers spoke of their life histories, their
political and religious beliefs, and so on - displaying at least
as much consistency across the transplant as any person who is
asked to discuss such matters on two separate occasions.
The three failures were difficult to characterise. They too learnt
to use their new bodies, to walk and talk as proficiently as the
others, but they were depressed, withdrawn, and uncooperative.
No physical difference could be found - scans showed that their
grafted tissue, and the residual portions of their Extra's brain,
had forged just as many interconnecting pathways as the brains
of the other volunteers. They seemed to be unhappy with a perfectly
successful result - they seemed to have simply decided that they
didn't want younger bodies, after all.
Gray was unconcerned; if these people were disposed to be ungrateful
for their good fortune, that was a character defect that he knew
he did not share. He would be utterly delighted to have
a fresh young body to enjoy for a while - before setting out to
wreck it, in the knowledge that, in a decade's time, he could
take his pick from the next batch of Extras and start the whole
process again.
There were "failures" amongst the Extras as well, but
that was hardly surprising - the creatures had no way of even
beginning to comprehend what had happened to them. Symptoms ranged
from loss of appetite to extreme, uncontrollable violence; one
Extra had even managed to batter itself to death on a concrete
floor, before it could be tranquillised. Gray hoped his own Extra
would turn out to be well-behaved - he wanted his old body to
be clearly sub-human, but not utterly berserk - but it was not
a critical factor, and he decided against diverting resources
towards the problem. After all, it was the fate of his
brain in the Extra's body that was absolutely crucial; success
with the other half of the swap would be an entertaining bonus,
but if it wasn't achieved, well, he could always revert to cremation.
Gray scheduled and cancelled his transplant a dozen times. He
was not in urgent need by any means - there was nothing currently
wrong with him that required a single new organ, let alone an
entire new body - but he desperately wanted to be first.
The penniless volunteers didn't count - and that was why he hesitated:
trials on humans from those lower social classes struck him as
not much more reassuring than trials on Extras. Who was to say
that a process that left a rough-hewn, culturally deficient personality
intact, would preserve his own refined, complex sensibilities?
Therein lay the dilemma: he would only feel safe if he knew
that an equal - a rival - had undergone a transplant before him,
in which case he would be deprived of all the glory of being a
path-breaker. Vanity fought cowardice; it was a battle of titans.
It was the approach of Sarah Brash's court case that finally pushed
him into making a decision. He didn't much care how the case
itself went; the real battle would be for the best publicity;
the media would determine who won and who lost, whatever the jury
decided. As things stood, he looked like a naive fool, an easily
manipulated voyeur, while Sarah came across as a smart operator.
She'd shown initiative; he'd just let himself (or rather, his
Extra) get screwed. He needed an edge, he needed a gimmick -
something that would overshadow her petty scheming. If he swapped
bodies with an Extra in time for the trial - becoming, officially,
the first human to do so - nobody would waste time covering the
obscure details of Sarah's side of the case. His mere presence
in court would be a matter of planet-wide controversy; the legal
definition of identity was still based on DNA fingerprinting and
retinal patterns, with some clumsy exceptions thrown in to allow
for gene therapy and retina transplants. The laws would soon
be changed - he was arranging it - but as things stood, the subpoena
would apply to his old body. He could just imagine sitting in
the public gallery, unrecognised, while Sarah's lawyer tried to
cross-examine the quivering, confused, wild-eyed Extra that his
discarded "corpse" had become! Quite possibly he, or
his lawyers, would end up being charged with contempt of court,
but it would be worth it for the spectacle.
So, Gray inspected Batch D, which were now just over nineteen
years old. They regarded him with their usual idiotic, friendly
expression. He wondered, not for the first time, if any of the
Extras ever realised that he was their clone-brother, too.
They never seemed to respond to him any differently than they
did to other humans - and yet a fraction of a gram of foetal brain
tissue was all that had kept him from being one of them. Even
Batch A, his "contemporaries", showed no sign of recognition.
If he had stripped naked and mimicked their grunting sounds,
would they have accepted him as an equal? He'd never felt inclined
to find out; Extra "anthropology" was hardly something
he wished to encourage, let alone participate in. But he decided
he would return to visit Batch D in his new body; it would certainly
be amusing to see just what they made of a clone-brother who vanished,
then came back three months later with speech and clothes.
The clones were all in perfect health, and virtually indistinguishable.
He finally chose one at random. The trainer examined the tattoo
on the sole of its foot, and said, "D12, sir."
Gray nodded, and walked away.
He spent the week before the transplant in a state of constant
agitation. He knew exactly which drugs would have prevented this,
but the medical team had advised him to stay clean, and he was
too afraid to disobey them.
He watched D12 for hours, trying to distract himself with the
supposedly thrilling knowledge that those clear eyes, that smooth
skin, those taut muscles, would soon be his. The only trouble
was, this began to seem a rather paltry reward for the risk he
would be taking. Knowing all his life that this day would come,
he'd learnt not to care at all what he looked like; by now, he
was so used to his own appearance that he wasn't sure he especially
wanted to be lean and muscular and rosy-cheeked. After
all, if that really had been his fondest wish, he could have achieved
it in other ways; some quite effective pharmaceuticals and tailored
viruses had existed for decades, but he had chosen not to use
them. He had enjoyed looking the part of the dissolute
billionaire, and his wealth had brought him more sexual partners
than his new body would ever attract through its own merits.
In short, he neither wanted nor needed to change his appearance
at all.
So, in the end it came down to longevity, and the hope of immortality.
As his parents had proved, any transplant involved a small but
finite risk. A whole new body every ten or twenty years was surely
a far safer bet than replacing individual organs at an increasing
rate, for diminishing returns. And a whole new body now,
long before he needed it, made far more sense than waiting until
he was so frail that a small overdose of anaesthetic could finish
him off.
When the day arrived, Gray thought he was, finally, prepared.
The chief surgeon asked him if he wished to proceed; he could
have said no, and she would not have blinked - not one his employees
would have dared to betray the least irritation, had he cancelled
their laborious preparations a thousand times.
But he didn't say no.
As the cool spray of the anaesthetic touched his skin, he suffered
a moment of absolute panic. They were going to cut up his
brain. Not the brain of a grunting, drooling Extra, not the
brain of some ignorant slum-dweller, but his brain, full
of memories of great music and literature and art, full of moments
of joy and insight from the finest psychotropic drugs, full of
ambitions that, given time, might change the course of civilisation.
He tried to visualise one of his favourite paintings, to provide
an image he could dwell upon, a memory that would prove that the
essential Daniel Gray had survived the transplant. That Van
Gogh he'd bought last year. But he couldn't recall the name
of it, let alone what it looked like. He closed his eyes and
drifted helplessly into darkness.
When he awoke, he was numb all over, and unable to move or make
a sound, but he could see. Poorly, at first, but over
a period that might have been hours, or might have been days -
punctuated as it was with stretches of enervating, dreamless sleep
- he was able to identify his surroundings. A white ceiling,
a white wall, a glimpse of some kind of electronic device in the
corner of one eye; the upper section of the bed must have been
tilted, mercifully keeping his gaze from being strictly vertical.
But he couldn't move his head, or his eyes, he couldn't even
close his eyelids, so he quickly lost interest in the view. The
light never seemed to change, so sleep was his only relief from
the monotony. After a while, he began to wonder if in fact he
had woken many times, before he had been able to see, but had
experienced nothing to mark the occasions in his memory.
Later he could hear, too, although there wasn't much to be heard;
people came and went, and spoke softly, but not, so far as he
could tell, to him; in any case, their words made no sense. He
was too lethargic to care about the people, or to fret about his
situation. In time he would be taught to use his new body fully,
but if the experts wanted him to rest right now, he was happy
to oblige.
When the physiotherapists first set to work, he felt utterly helpless
and humiliated. They made his limbs twitch with electrodes, while
he had no control, no say at all in what his body did.
Eventually, he began to receive sensations from his limbs, and
he could at least feel what was going on, but since his
head just lolled there, he couldn't watch what they were doing
to him, and they made no effort to explain anything. Perhaps
they thought he was still deaf and blind, perhaps his sight and
hearing at this early stage were freak effects that had not been
envisaged. Before the operation, the schedule for his recovery
had been explained to him in great detail, but his memory of it
was hazy now. He told himself to be patient.
When, at last, one arm came under his control, he raised it, with
great effort, into his field of view.
It was his arm, his old arm - not the Extra's.
He tried to emit a wail of despair, but nothing came out.
Something must have gone wrong, late in the operation, forcing
them to cancel the transplant after they had cut up his
brain. Perhaps the Extra's life-support machine had failed; it
seemed unbelievable, but it wasn't impossible - as his parents'
deaths had proved, there was always a risk. He suddenly felt
unbearably tired. He now faced the prospect of spending months
merely to regain the use of his very own body; for all he knew,
the newly forged pathways across the wounds in his brain might
require as much time to become completely functional as they would
have if the transplant had gone ahead.
For several days, he was angry and depressed. He tried to express
his rage to the nurses and physiotherapists, but all he could
do was twitch and grimace - he couldn't speak, he couldn't even
gesture - and they paid no attention. How could his people have
been so incompetent? How could they put him through months of
trauma and humiliation, with nothing to look forward to but ending
up exactly where he'd started?
But when he'd calmed down, he told himself that his doctors weren't
incompetent at all; in fact, he knew they were the best in the
world. Whatever had gone wrong must have been completely beyond
their control. He decided to adopt a positive attitude to the
situation; after all, he was lucky: the malfunction might have
killed him, instead of the Extra. He was alive, he was
in the care of experts, and what was three months in bed to the
immortal he would still, eventually, become? This failure would
make his ultimate success all the more of a triumph - personally,
he could have done without the set-back, but the media would lap
it up.
The physiotherapy continued. His sense of touch, and then his
motor control, was restored to more and more of his body, until,
although weak and uncoordinated, he felt without a doubt that
this body was his. To experience familiar aches and twinges
was a relief, more than a disappointment, and several times he
found himself close to tears, overcome with mawkish sentiment
at the joy of regaining what he had lost, imperfect as it was.
On these occasions, he swore he would never try the transplant
again; he would be faithful to his own body, in sickness and in
health. Only by methodically reminding himself of all his reasons
for proceeding in the first place, could he put this foolishness
aside.
Once he had control of the muscles of his vocal cords, he began
to grow impatient for the speech therapists to start work. His
hearing, as such, seemed to be fine, but he could still make no
sense of the words of the people around him, and he could only
assume that the connections between the parts of his brain responsible
for understanding speech, and the parts which carried out the
lower-level processing of sound, were yet to be refined by whatever
ingenious regime the neurologists had devised. He only wished
they'd start soon; he was sick of this isolation.
One day, he had a visitor - the first person he'd seen since the
operation who was not a health professional clad in white. The
visitor was a young man, dressed in brightly coloured pyjamas,
and travelling in a wheelchair.
By now, Gray could turn his head. He watched the young man approaching,
surrounded by a retinue of obsequious doctors. Gray recognised
the doctors; every member of the transplant team was there, and
they were all smiling proudly, and nodding ceaselessly. Gray
wondered why they had taken so long to appear; until now, he'd
presumed that they were waiting until he was able to fully comprehend
the explanation of their failure, but he suddenly realised how
absurd that was - how could they have left him to make his own
guesses? It was outrageous! It was true that speech, and no
doubt writing too, meant nothing to him, but surely they could
have devised some method of communication! And why did they look
so pleased, when they ought to have been abject?
Then Gray realised that the man in the wheelchair was the Extra,
D12. And yet he spoke. And when he spoke, the doctors
shook with sycophantic laughter.
The Extra brought the wheelchair right up to the bed, and spent
several seconds staring into Gray's face. Gray stared back; obviously
he was dreaming, or hallucinating. The Extra's expression hovered
between boredom and mild amusement, just as it had in the dream
he'd had all those years ago.
The Extra turned to go. Gray felt a convulsion pass through his
body. Of course he was dreaming. What other explanation could
there be?
Unless the transplant had gone ahead, after all.
Unless the remnants of his brain in this body retained enough
of his memory and personality to make him believe that he, too,
was Daniel Gray. Unless the brain function studies that had localised
identity had been correct, but incomplete - unless the processes
that constituted human self-awareness were redundantly duplicated
in the most primitive parts of the brain.
In which case, there were now two Daniel Grays.
One had everything: The power of speech. Money. Influence.
Ten thousand servants. And now, at last, immaculate health.
And the other? He had one thing only.
The knowledge of his helplessness.
It was, he had to admit, a glorious afternoon. The sky was cloudless,
the air was warm, and the clipped grass beneath his feet was soft
but dry.
He had given up trying to communicate his plight to the people
around him. He knew he would never master speech, and he couldn't
even manage to convey meaning in his gestures - the necessary
modes of thought were simply no longer available to him, and he
could no more plan and execute a simple piece of mime than he
could solve the latest problems in grand unified field theory.
For a while he had simply thrown tantrums - refusing to eat,
refusing to cooperate. Then he had recalled his own plans for
his old body, in the event of such recalcitrance. Cremation.
And realised that, in spite of everything, he didn't want to
die.
He acknowledged, vaguely, that in a sense he really wasn't Daniel
Gray, but a new person entirely, a composite of Gray and the Extra
D12 - but this was no comfort to him, whoever, whatever, he was.
All his memories told him he was Daniel Gray; he had none from
the life of D12, in an ironic confirmation of his long-held belief
in human superiority over Extras. Should he be happy that he'd
also proved - if there'd ever been any doubt - that human consciousness
was the most physical of things, a spongy grey mess that could
be cut up like a starfish, and survive in two separate parts?
Should he be happy that the other Daniel Gray - without a doubt,
the more complete Daniel Gray - had achieved his lifelong ambition?
The trainer yanked on his collar.
Meekly, he stepped onto the path.
The lush garden was crowded like never before - this was indeed
the party of the decade - and as he came into sight, the guests
began to applaud, and even to cheer.
He might have raised his arms in acknowledgement, but the thought
did not occur to him.
