I don't have any superstitions about Friday the 13th but I do believe in good luck and bad luck! And I have one big superstition about the day after your birthday usually being pretty awful. It didn't happen this year, but often times bad things have happened the immediate day after my birthday. One year my dog died, etc. etc. Bad stuff that made me believe it's kind of a thing to expect.

I'll be taking sins13 for my answer! Thank you!
