Lol, I don't believe in that, it's just the same as other Fridays, why is it specifically 13th? Why not 21th? Or 17th? And so on. I never had anything bad happen on Friday 13th, nor has any of my entire family, including cousins, aunts, uncles, grandparents, and so forth. I honestly didn't notice any difference in Friday 13th, and didn't know this happens until I read this. But if others want to think that, I say "good luck." Bye!
