Question?

Okay so my mom has always told me that she thought that wicca was evil and that if I ever converted to it she would throw me out. However, the other day we were talking and she said that she believes in Tarot readings and Rune reading. She loves Sylvia Brown and thinks that she is a true divinator. I should her my runes and she was really excited and I told her that I was thinking about getting tarot cards as well and she was all for it. My step-dad has an aunt who does tarot readings, i have never met her and I told my mom I would like to and once again that was okay.
So my question is why is it okay for me to surround myself with Magickal people and items and even practice so of the divinations acts but its not okay for me to be a full wiccan.
I am thinking about telling her but I just don't know how to go about it without getting kicked out. I really can't afford to live on my own. Maybe I will just wait and tell her when I move out. I am acutally looking forward to living on my own and being able to set up my magickal alter and items the way I wish and practice whenever I want.
I am staying with my friend Aeitha for a whole week in January b/c her parents are going out town. so we will get to practice and do some rituals that are long over due! I can't wait.
well guys that is it for now Blessed Be and Merry Meet!
