If you broke a mirror, would you worry about bad luck even if you're not superstitious? Would you walk under a ladder or cross a black cat's path on a dare? Is there anything you're superstitious about?
I've never done one of these before, but this one piqued my interest. I'm not superstitious in the slightest, and I don't believe in things like bad or good luck. But I do tend to do things like walk around ladders or not open umbrellas indoors, not because I think they are unlucky, but because they are things that are slightly taboo in our society (because of superstition) and so I have this notion that they are "bad" things to do. This concept is interesting to me: that I am not superstitious, but that the superstitious beliefs of others can still influence my actions.
Of course, whenever I meet a black cat, I always try to cross its path, because I want to pet it.
