So as we progress through the book it’s obvious to see Holden is quite ‘all there.’ He has a couple of excuses, though. We learn that he had a brother that he was really close with, Allie. He died and when he did Holden pretty much lost it. “I was only thirteen, and they were going to have my psychoanalyzed and all, because I broke all the windows in the garage. I don't blame them. I really don't. I slept in the garage the night he died, and I broke all the goddam windows with my fist, just for the hell of it. I even tried to break all the windows on the station wagon we had that summer, but my hand was already broken and everything by that time, and I couldn't do it. It was a very stupid thing to do, I'll admit, but I hardly didn't even know I was doing it, and you didn't know Allie” (page 39). Holden had a lot to deal with and it’s apparent that he was institutionalized at some point. But we aren’t really given all the details, even at the end. I guess it gives the book more suspense, but it also gives us a lot to think about. I think this is why I liked this book so much.
