It actually took me about two-thirds of the book to decide I liked it. The story is told in first person, and after a while I got the distinct feeling that I was spending a weekend with the kind of person I hate talking to at parties: people who hate everything and everybody, and won't shut up about it.
(OK, I realize that I've already told you that I totally relate to Caulfield, and also that he reminds me of the kind of person I hate talking to at parties...so does that mean I would hate talking to myself at a party? Perhaps that's an existential question for another time...)
The narrative picks up shortly after Caulfield has been expelled, and follows him as he kills time for three or four days until he has to return home. One by one, he encounters a number of characters from his past, old roommates, classmates, girlfriends, and a few other sad souls along the way. Each of these encounters is half-cocked and quickly runs out of gas. The novel is almost a stream-of-consciousness rant from a frustrated kid who pretends to hate the world in order to cover up the fact that he cares about it so much. Caulfield claims he doesn't like anyone he encounters, though his actions suggest a deep desire to be accepted by them, and even when he encounters someone he doesn't admire, he still feels horrible when he realizes he may have offended them with his aloof persona. Everything he says is designed to promote an insensitive image, when in reality he's hypersensitive to everything he comes into contact with.

In that way and others, Caulfield is no different than anyone, especially in our teenage form. He lives in Pete Townshend's "Teenage Wasteland" as a smart but unmotivated underachiever. He doesn't seem to know what he wants to do with his life, and isn't sure how to make a career out of the few things he does genuinely appreciate. In a way, he's wise beyond his years, but still to young to understand the true meaning of what he knows. He seeks out advice from people around him, but doesn't really listen to them.
One of the most powerful sequences in the book is when he seeks out his old teacher Mr. Antolini, who sits him down and tries to talk some sense into him. Antolini is one of the few people who seems to understand Caulfield, and is deeply concerned about the path his former student is taking.
"I have a feeling that you're riding for some kind of a terrible, terrible fall," he says. "But I honestly don't know what kind."
He goes on to share a pretty deep proverb from a psychoanalyst named Wilhelm Stekel:
The mark of the immature man is that he wants to die nobly for a cause, while the mark of the mature man is that he wants to live humbly for one.
Sadly, even this powerful exchange ends badly, and you get the feeling that this valuable advice is lost in the confusion.
Caulfield's anchor is his little sister, whom he finally seeks out late in the book. Phoebe is the only person who seems to be able to cut through his wall and get him to open up about everything that's tearing him up inside. After farting around in clubs and badgering old girlfriends and school buddies for three days, Caulfield sneaks into his parent's home to see Phoebe, and when he breaks down at her bedside, the reality of his character comes to life in a heartbreaking way.

It's very possible that without the benefit of a Lit professor or outside research, I have missed some critical theme or message in this book. But that's almost intentional. I didn't want to look for what everyone else had already picked out; I wanted to find what I found on my own, and that's what I've written here. So there's a pretty good chance that everything before this is just me transposing the plot and character on my own life. Some might say that's what literature is about. I'm just warning you in case anyone is reading this as research for a book report.
