OK. So here she is.
While I was watching a lady decided to climb over the rocks so someone could take a picture of her. She fell in. Obviously thought it was funny, but I was just waiting for her to get out of the shot. I did think of shouting "You have legs not flippers, so flip off" but the little monitor that sits on my shoulder told me it would probably not be as well received in real life as it sounded in my head.
