Fairy tales have a moral: Stay on the path. Don't trust wolves. Don't steal things, not even things you think no normal person would care about. Share your food but don't trust people who want to share their good with you; don't eat their shiny red apples, not their candy houses, nor any of it. Be nice, always nice, and polite to everyone: kings and beggars, witches and wounded bears. Don't break a promise.
