WC?

Mrs. Skipper's class at Britton Elementary in Hilliard, Ohio like the Bill and Pete books. "We are wondering in the book, BILL AND PETE GO DOWN THE NILE, what does WC mean on the bathroom door?"

Tomie: Excellent question! WC stands for Water Closet. Water Closet was the original name for a room with a toilet. My house has four water closets although three of them could correctly be called bathrooms as three of them have toilets AND showers.
