Catcher In the Rye (Pages 135-170)

I got to the point in the book that solves my questions about Mr. Lough's comic strip from my last post. It's just a brief section, but Holden is explaining to his sister that he only cares about few things. He also says that there's only one thing he would want to be when he gets older, and that is a catcher in the rye. The name of the book. Apparently he means that when a bunch of kids are playing in the rye by a cliff, he would be aqt the edge of the cliff, waiting for kids to run off course so he can catch them and prevent them from falling off the cliff. I don't really understand how that's something you can just want to do, but whatever works for him. Why can't he just be a firefighter or an astronaut? Maybe that's the point. Maybe he's a special kind of guy that only wants to help others. Anyways I have about 40 pages left so we'll see. Also, Mr Clough gave us Lord of the Flies today.
