I can't think of any superstitions I have....I believe more in a Karmic sense of what comes around goes around and assume that what I do unto others will eventually come back to me....that's kinda like superstition, right?
I don't have a "lucky" number, but I favor even numbers over odds and 12 is my favorite.
I wish I believed in luck and superstition...cuz I could really use some good luck to come my way right about yesterday or so!
