What do you want to say?
Have you thought about that? About the lessons people will learn from reading your story?
Some morals are written out plainly. Maybe the writer wrote the whole story about forgiveness. Or friendship. Or God's mercy. From beginning to end, the story winds its way through the highlights of it's theme.
Some morals are more subtle. What choices are rewarded in your story? What choices gets the characters into trouble? Who wins in the end? Maybe not even the author knows what she is saying until it is all written. That happens for me sometimes.
I don't see a lot of inspiring lessons in the original Sleeping Beauty tales (do you?), but I think it provides an easy base for whatever you want to say.
Which brings me back to my original question:
