When I was growing up my mom had this superstition that it was bad luck to wear anything new on a Friday.
So we never did.
After I moved out one Friday night there was a party, and I had a sweater that was brand new, I thought about the superstition but I wore it anyway.
That night I got into a fight and got hit in the mouth with a beer mug splitting my lip through to the teeth. The blood from my mouth soaked the chest of the sweater, it was ruined.
