My sister knows now.
We were talking the other day, and she was telling me (via chat) about some movie she was buying at Amazon, and I said, you can buy me a book there! So she asked me what I wanted, and after a few minutes told her the one I'd been waiting to get (Natural Witchery). She said, "Are you going Wiccan?". We talked for a few minutes about that I didn't really know where I was going, just in a more magical direction, and sent her to my blog. So that was pretty positive. :)
I still don't think my dad could handle it very well, but one thing at a time, right?
