Someone should make a game about: Misperception

I left the office one night last week and saw a woman holding a shark walking towards me. If this had been Hove, I might have been surprised, but since it’s Brighton I went along with it. (In Hove people walk their sharks on leads.) When I looked again, though, she wasn’t holding a shark at all. She was holding a large sheet of blue card, bent over on itself with its cream reverse peeking out at the bottom.
