The thing that is most interesting about people is the way they are when no one is looking at them or the way they are when they are in private.
Of course, sometimes when you write personally, you are also writing about society, obliquely reflecting topical issues, but not in a way that people would expect you to or in the way that someone trying to make a point would.
Sometimes I listen to songs by very smart writers who assume that the world is a civil place with certain formalities that people follow, but I don't see things that way. My own experience tells me that life is not like that.
