When we are very small, we have read about many fairy tales. Our parents will read them to us before we sleep. These fairy tales tell us about wonderful stories, such as the prince and princess. They show the children the importance of being a nice kid. But when I grow up, I start to see some movies about the dark side of fairy tale. Take the Snow White for example, it begins with the happy ending of Snow White. At her wedding, the witch came and cursed her child. It is not a happy ending at all. What I have read before is completely changed. The dark fairy tales are not bad sides at all. They tell me the world is not as perfect as I think, so that I can better accept the difficulty.
