One weekend, a wife and a husband (丈夫) went to visit a shop in Tokyo. After they got back
home, they couldn't find their camera (照相机). They thought the camera must be in the shop. After
a few weeks, they went to that shop again and the boss of the shop gave their camera back to them.
When their pictures 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 (纸) 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".
