"You never saw so many mean guys in your life. For instance, if you were having a bull session in somebody's room, and somebody wanted to come in, nobody'd let them in if they were some dopey, pimply guy. Everybody was always locking their door when somebody wanted to come in. And they had this goddam secret fraternity that I was too yellow not to join. There was this one pimply, boring guy, Robert Ackley, that wanted to get in. He kept trying to join, and they wouldn't let him. Just because he was boring and pimply.”
