Yeah, you never know who'll turn into a wolf or something. It could even be you... Though wolves are kinda cool.

I love the line in one of Terry Pratchett's Discworld books, where Esme says something like, "half-moons are more dangerous. You are never quite sure which way they're going to go. There's always a feeling that they could go the other way." - was it in 'Carpe Jugulum'? I forget. Time to reread!
