Kevin is 15, and is close friends with your son, David, who's in high school. The two of them have been friends for years, and you and Kevin's father treat each others kids like they were your own.
Kevin hangs around your house a lot during the summer. The only problem is, he never remembers a swim suit, so ends up swimming in his clothes. That wouldn't be a problem, except he likes cut off jeans. You've asked him numerous times not to swim in them, because the threads can get lose and jam the filter.
You just got home, and Kevin was coming out of the pool.
What happens to Kevin? David knows Kevin isn't supposed to be swimming in those: Is he in trouble as well?
