I hope 13 is a lucky number for me. I have it tattoed on me in about 3 different places so far in various ways. In general I am a very superstitious person. For the most part I don't worry about the stuff like mirrors, ladders, black cats and the like. For me it has morphed into a slightly OCD thing where I feel if I dont do certain things, bad luck will come right in the front door. And the way my life has played out...I dont need any more bad luck.
13 is my lucky number as well. I was born on Friday the 13th. Glass doesn't bother me. Black cats are really the only thing that freaks me out. If one goes in front of my car...I put an X on the windshield. Don't ask me why...cuz I don't know. Could be that I HATE cats (sorry cat lovers). I also...do knock on wood every so often.
