Superstition

Why Is Friday the 13th Considered So Unlucky?
Ah, yes. Another Friday the 13th, when the ultra-superstitious will hide at home with the shades drawn and hope nothing ill befalls them. But have you ever wondered why this particular date has the power to freak out so many people?
Friday The 13th!
OK, so what happens if you cross the path of a black cat and a white cat at the same time? Do the two cancel each other out? I mean will you have bad luck?... This is a serious issue! Anyone else have issues with Friday the 13th's!
