The Catcher in the Rye - Pg 121

  The best thing, though, in that museum was that everything always stayed right where it was. Nobody'd move. You could go there a hundred thousand times... Nobody'd be different. The only thing that would be different would be you. Not that you'd be so much older or anything. It wouldn't be that, exactly. You'd just be different, that's all. You'd have an overcoat on this time. Or the kid that was your partner in line the last time had got scarlet fever and you'd have a new partner. Or you'd have a substitute taking the class, instead of Miss Aigletinger. Or you'd heard your mother and father having a terrific fight in the bathroom. Or you'd just passed by one of those puddles in the street with gasoline rainbows in them. I mean you'd be different in some way--I can't explain what I mean. And even if I could, I'm not sure I'd feel like it.
