I read Tarot cards. I think there is a misconception about us. What most Tarot card readers practice is what's called white magick. (yes with a k). It is more about finding light, love and peace. Spells are frowned upon because there is the universal law of three...whatever you do to someone else comes back to you threefold. The cards I read provide guidance and wisdom. However, everyone has free will, so the choices are always with the querant (term for someone I read for.)
Out of curiosity, did she tell you that her friend did a reading on you and her specifically?
