Usually I like riding on trains, especially at night, with the lights on and the windows so black, and one of those guys coming up the aisle selling coffee and sandwiches and magazines. I usually buy a ham sandwich and about four magazines. If I'm on a train at night, I can usually even read one of those dumb stories in a magazine without puking. You know. One of those stories with a lot of phony, lean-jawed guys named David in it, and a lot of phony girls named Linda or Marcia that are always lighting all the goddam Davids' pipes for them. I can even read one of those lousy stories on a train at night, usually. But this time, it was different. I just didn't feel like it. I just sort of sat and not did anything. All I did was take off my hunting hat and put it in my pocket.
