I hate fist fights. I don’t mind getting hit so much – although I’m not crazy about it, naturally – but what scares me most in a fist fight is the guy’s face. I can’t stand looking at the other guy’s face, is my trouble. It wouldn’t be so bad if you could both be blindfolded or something. It’s a funny kind of yellowness, when you come to think of it, but it’s yellowness, all right. I’m not kidding myself.

The Catcher in the Rye. Holden in Chapter 13. Holden hates fist fights because he is strongly pacifist.
