I don't know who I am most of the time

People are always talking about freedom. Freedom to live a certain way, without being kicked around. Course the more you live a certain way, the less it feel like freedom. Me, uhm, I can change during the course of a day. I wake and I'm one person, when I go to sleep I know for certain I'm somebody else. I don't know who I am most of the time. (Billy the Kid)
