David came to show me his post-bath hairdo. It was both curled under and sticking up. It was quite remarkable. He said it was a happy accident, and then he explained. "Let's say you're drawing a picture of a human and you make a mistake. You draw like this and like this." David draws obviously squared off limbs in the air. "You could turn it into a robot! It's a happy accident." That's what David learned in art class today, a life lesson.
