Pulled from an essay of mine elsewhere:
I write fairy tales because they can be dangerous, because they can allow us to explore truths and deceptions we would often prefer to ignore. That even in a place of seeming safely, you can find yourself trapped in a crystal coffin. That you can lose your eyesight thanks to forces beyond your control. That you may leave bloodstains as you walk before you reach the end of your quest. That sometimes, love may be tangled with the secrets of the past; that opening doors can be dangerous, or can bring you freedom. The original tale of Bluebeard is all about this. I don’t argue that you should believe in all parts of fairy tales. But I do believe you should listen. It’s less dangerous that way.
So there you go.
