By the end of the first year the joke had worn thin, and the inability of others to see the humor of it had become depressing. "Oh, you mean your father worked there," they would say when he tried to explain it, and their eyes, as often as not, would then begin to film over with the look that people reserve for earnest, obedient, unadventurous young men. Before long (and particularly after the second year, with both his parents dead) he had stopped trying to explain that part of it, and begun to dwell instead on other comic aspects of the job: the absurd discrepancy between his own ideals and those of Knox Business Machines; the gulf between the amount of energy he was supposed to give the company and the amount he actually gave. "I mean the great advantage of a place like Knox is that you can sort of turn off your mind every morning at nine and leave it off all day, and nobody knows the difference."
