"I can do the kinds of witch things that are about being a witch," says Helen, "but I don't always decide to do all the witch things that are about witches deciding to do stuff some particular way. Because - if I just feel like doing something some way, and it's not hurting anybody just by me doing that, then that's important. Even if I don't have a really good reason, or if people think I'm weird, it's important that I want to do the thing."
