What does this quote mean “I’m standing on the edge of some crazy cliff. What I have to do, I have to catch everybody if they start to go off the cliff- I mean if they’re running and they don’t look where they’re going I have to come out from somewhere and catch them. That’s all I'd do all day. I’d just be the catcher in the rye and all” No links please
