Oh, Friday the 13th, dun, dun, daaaa. :) As long as you're not a Templar Knight I think you're all right. I believe the bad luck of Friday the 13th came because that was the day the Catholic Church destroyed the Templar Knights. Now the curse sort of has a life of its own as billions of people around the world know or have heard that it is a "bad" luck day.
I have always found it to be a good luck day. A writer friend of mine got married on the 13th because she felt like the number 13 is good luck for her. She celebrated 25 years this year.
So, I wish for you all the best of luck today and always. Do you have any Friday the 13th stories?
