The Charlie Brown Theory of Personality.
Charlie Brown = Neuroticism
Charlie Brown is a model neurotic. He is prone to depression and anxiety and paralyzing fits of over-analysis. Constantly worrying if he is liked or respected, he has a perpetual, usually dormant crush on the little redheaded girl, taking small joys in her foibles (like biting her pencil) that may make her more attainable. He is noted for his inability to fly a kite.
This is what Charlie Brown would look like if he was a real boy. I think he looks like a cabbage patch kid also. I think he is cute. He just needs love.
