One weekend, a wife and a husband went to visit a shop in London. After they got back home, they couldn't find their camera. They thought the camera must be in the shop. After a few weeks, they went to that shop again and the boss gave their camera back to them.
When their picture of the camera came out, the husband saw two pictures he did not take. One is a man standing at the door of the shop. In his hand there is a piece of paper with some words on it “I find your camera”. The other is a boy with a piece of paper in his hand. There are some words on the paper too, “I take the pictures.”
