You gotta love superstition. It’s widely considered to be the unluckiest day of the year today, but does anyone really know why? Wikipedia has a good article, and Snopes debunks most of the myths. The conclusions? Nobody knows for sure.
I’ve always rather liked Friday the 13th. I don’t believe there’s anything inherently lucky about it—good or bad—any more than any other day. Although today I walked downtown to get my haircut and got caught in the rain walking back—without a jacket. Bad luck? You decide. :)
