Well, I once had a relationship with a wannabe Wicca who beleived in the magic arts. We met up with some of her like-minded friends who attempted to ridicule me because of my religion so I told them that I would rethink my beliefs if they could demonstrate 'magic' to me, levitation being the one that they claimed they could achieve.
I put my pint down and asked that they raise it, even an inch, from the table surface. The only time it moved was when I picked it up to have another drink from it. She accused me of ridiculing her friends, I told her to go hunt for fairys at the bottom of her garden and advised that she no longer call me. I was threatened by one of her friends who shouted 'I'll hex you' to which I replied 'smashing, thanks very much'. The idiot actually believed he cursed me and couldn't understand why I wasn't scared. Blooming delusional.
