There are public toilettes in Paris. They used to cost a franc, when there were francs. Now they are gratuit, free. This particular one kept opening and closing, so we thought we'd stand guard while it was being used by one of us. Then it shut and didn't open. So one of us, who will remain nameless, got to use it. We were laughing very hard and some sales men from the clothing store were watching us curiously. After the door opened again, I decided a picture was in order to remember how funny this was.
