Why are we the way we are?

Sitting here traveling without moving(sitting in a chair brain storming) and I asked myself why do people do the things they do? Now I personally have no room to talk, but im speaking anyway! I don't want to get into detail's on what prompt this enternal coversation but people sure can be funny. It's like you can lie to yourself but don't try and get me to believe your lie. Like they say in the old days "my name is Bennett and I ain't in it."
