I think you make your own luck when it comes to things like this. It's usually the people that get all worried and agitated about the date that end up having a bad day.
Me... I've always had a good day on Friday the 13th.
Maybe I just look at it more positively than the norm.
So, in celebration...
Oh and Noodles... you said 13 is good luck in your parents' religion? What religion are they?
