In our family 13 is a lucky number, as it is the date upon which my wife Joanne was born.  

Throughout our relationship, everyone has always reinforced this reality by telling me how "lucky" I have been to be with her and, more than anyone else, I readily agree!

In addition, for many years my law firm thrived on the 13th floor, I came of age at 13 and Wilt wore number 13.

So, in my experience, "unlucky 13" is a fallacy and I wish you all a good and LUCKY day!
