Friday the 13th

Okay, so, it is Friday the 13th. Which brings up the line of thinking about superstitions. I am not a very superstitious person. I don't really get the whole "don't walk under a ladder", "don't open an umbrella instead the house", all those kinds of things. Either they are unfounded, or I just have bad luck all the time! Hmmm, don't know can't really think of one that I believe in right now, How about you?
