Friday the 13th

Today is Friday the 13th in case you haven't taken a look at the calendar. For some people this day means absolutely nothing with the exception of it finally being the end of the workweek. For another group of people this day means something more and superstitions. I've never really got into the whole superstition thing like walking under a ladder or breaking a mirror but I do know people who do, I'm sure you do as well. Does Friday the 13th mean anything more than just another day on the calendar to you?
