Bob: That's one of the nice things about painting landscapes. If you paint a portrait and you get someone's eye out of place, it's going to be wrong. But if you get a crooked line or a strange colour when you paint a tree, someone will come up to you and say, "I know that tree. We went to different schools together."
It's not crazy talk, it's zen. Don't think about it. Just accept it for its strange wisdom, and move along.
