for him. "Yes. Yes, it would be good to have him around. I have to confess I miss the old monster at least as much as you do."
"Monster?"
"In a manner of speaking."
"Ah. Yes. A manner of speaking."
When George had gone, Andrew replayed the conversation in his mind, puzzling over its twists and turns and trying to see why he had been so badly off balance throughout it. It had been George's use of idiomatic phrases and colloquial language, Andrew decided, that had caused the problems.
Even after all this time, it was still difficult sometimes for Andrew to keep pace with humans when they struck out along linguistic pathways that were something other than the most direct ones. He had come into being equipped with an extensive innate vocabulary, a set of grammatical instructions, and the ability to arrange words in intelligible combinations. And through whatever fluke in his generalized positronic pathways it was that made Andrew's intelligence more flexible and adaptable than that of the standard robot, he had been able to develop the knack of conversing easily and gracefully with humans. But there were limits to his abilities along that line.
The problem was only going to get worse as time went along, Andrew realized.
Human languages, he knew, were constantly in a state of flux. There was nothing fixed or really systematic about them. New words were invented all the time, old words would change their meanings, all sorts of short-lived informal expressions slipped into ordinary conversation. That much he had already had ample reason to learn, though he had not done any kind of scientific investigation of the kinds of changes that tended to take place.
The English language, which was the one Andrew used most often, had altered tremendously over the past six hundred years. Now and then he had looked at some of Sir's books, the works of the ancient poets-Chaucer, Spenser, Shakespeare-and he had seen that their pages were sprinkled with footnotes to explain archaic word usage to modern readers.
What if the language were to change just as significantly in the next six hundred years? How was he going to be able to communicate with the human beings around him, unless he kept up with the changes?
Already, in one brief conversation, George had baffled him three times. "Like grandfather, like grandson." How simple that seemed now that George had explained it-but how mysterious it had been at first.
And why had George called him a "hunk of tin," when George surely knew that there was no tin in Andrew's makeup whatsoever? And-it was the most puzzling one of all-why should George have called Sir a "monster," when that was plainly not an appropriate description of the old man?
Those were not even the latest modern phrases, Andrew knew. They were simply individual turns of phrase, a little too colloquial or metaphorical for instant handling by Andrew's linguistic circuitry. He would face far more mystifying ways of speech in the outside world, he suspected.
Perhaps it was time for him to update some of his linguistic documentation.
His own books would give him no guidance. They were old and most of them dealt with woodworking, with art, with furniture design. There were none on language, none on the ways of human beings. Nor was Sir's library, extensive as it was, likely to be of much use. No one was living in the big house just now-it was sealed, under robot maintenance-but Andrew still could have access to it whenever he wanted. Nearly all of Sir's books, though, dated from the previous century or before. There was nothing there that would serve Andrew's purpose.
All things considered, the best move seemed to be for him to get some up-to-date information-and not from George. When Andrew turned to George at the time he had wanted to start wearing clothing, he had had to fight his way through George's incomprehension and a certain amount of George's condescending amusement. Though he doubted that George would treat him the same way in this matter, he preferred not to find out.
No, he would simply go to town and use the public library. That was the proper self-reliant thing to do-the correct way for a free robot to handle a problem, he told himself. It was a triumphant decision and Andrew felt his electropotential grow distinctly higher as he contemplated it, until he had to throw in an impedance coil to bring himself back to equilibrium.
To the library, yes.
And he would dress for the occasion. Yes. Yes. Humans did not
