Let me put it this way, I come from a long, long line of CRAZY Russian women who initiated superstitions! Don't pass the salt directly to me, put it down first. Don't put shoes on a chair. Don't look at a new moon through glass, and if you do, you must stop what you are doing and undo the 'bad luck' by spitting on your thumb and turning three times anti clockwise.... (this includes pulling off to the side of the road if you should happen to see the new moon BY MISTAKE through the windshield) need I say more?

However, the friday the 13th thing doesn't really figure into all this other silliness, so yes, it will all be fine. Oh, and the black cat thing.... super
good luck you'll be happy to know.
