"Do you think spells work?" Sometimes this will send the woman off on a long blab, but if the conversation needs to be kept going, the follow-up routine is:
"The reason I'm asking is because my friend over there met a girl in a club last week. He wasn't interested in her sexually, because she wasn't really his type." (Here the woman might say "Sure," in which case you reply "No, really!" and touch her arm or waist.) "Anyway, she hung out at his house and after she left, he found a metal ring wrapped around a scroll and some feathers under his couch. Well, he took it to a magick store and they said it was an attraction spell. And now, the strange thing is, he can't stop thinking of her. Do you think it's the spell or just psychological?"
