My son's birthday is on February 13 and when it falls on Friday, he considers it his good luck day.
And, I married Alan on Friday the 13th, a black cat crossed our path the night before and I think it was also a full moon. A rainbow appeared just as we were saying our vows. For me, Friday the 13th has been the most wonderful day that ever happened in my life. And, it just keeps getting better!
