Rumplestiltskin, by Anne Sexton

This is from a book called Transformations, which I read long long ago, when I was learning to tell stories myself, before the term "fanfiction" was invented. I learned two things from this book that I relearned when I discovered fanfiction: when you retell a story that I know, no matter how well I know it and no matter how well I love it, I'll learn something interesting about the story from your retelling; and when you retell a story that I know, I'll learn something really interesting about you.
