I've never been superstitious about Friday the 13th. I was born on Friday the 13th. My father was born on Friday the 13th as well.
I'm not superstitious about the number 13 either. I was born in the 13th month of the 1960's, on the 13th day. My first name starts with an M - the 13th letter of the alphabet. My last name starts with an M, too. I have 13 letters in my first and last name. "Ah!", you say, "why didn't you count your middle name?" I didn't get a middle name, just an initial - M. I was born in South Carolina. Count the letters - 13 again. My mom's name is Denise. My dad's name was Michael. 13 letters between the two of them. I could go on. When I was a kid, I would collect every instance of 13 I could legitimately claim. Then again, I've never been superstitious about Numerology either.
