I read about a girl getting her period in a book. When I asked my sister what it was, she said it's when you pee blood. Close, I guess. Somehow I got the impression that you had your period for seven days, then had one day of relief, followed by another seven days.... Yeah, my mom had a good laugh while explaining THAT.
