It reminds me of something I read in a book a while back: a mother's memoir of raising a big family with one of the children, Karen, born with cerebral palsy. She taught the kids the Ten Commandments and explained "adultery" as "impurity."

So Karen's little brother Rory, about three at the time, dropped his pants and took a leak while playing in the front yard. Karen tattled to her mother: "Mama! Rory's committing adultery! He's got his pants down, and he's peeing in public!"
