I heard somebody open and shut the gate to the barn lot, but I didn't look around. If I didn't look around it would not be true that somebody had opened the gate with the creaky hinges, and that is a wonderful principle for a man to get hold of... What you don't know know don't hurt you, for it ain't real. They called that Idealism in my book I had when I was in college, and after I got hold of that principle I became an Idealist... If you are an Idealist it does not matter what you do or what goes on around you because it isn't real anyway.
