I didn’t attain a state of partytime that night. Neither did I exhibit adult common sense and give up, go home, watch some ancient movie, and fall asleep on my futon. The tension those three weeks had built up in me drove me like the mainspring of a mechanical watch, and I went ticking off through nighttown, lubricating my more or less random progress with more drinks. It was one of those nights, I quickly decided, when you slip into an alternate continuum, a city that looks exactly like the one where you live, except for the peculiar difference that it contains not one person you love or know or have even spoken to before. Nights like that, you can go into a familiar bar and find that the staff has just been replaced; then you understand that your real motive in going there was simply to see a familiar face, on a waitress or a bartender, whoever . . . This sort of thing has been known to mediate against partytime.
