Holden, through out the book, searches for companionship. For instance, he calls up Sally. But on his date with her, he proposes marriage, calls her a pain in the ass, and then gets annoyed with her (as though she's the reason the date went bad.) This is similar to all his conquests for companionship- he doesn't feel anyone is "good" enough for him (they are "phony") so he doesn't have many, if any, friends.
