Good evening! I am a Lost and Found box. I have a name and you can call me Mr. Magic. Now, you can see a key, a yellow eraser and a blue pencil in me. 

I am in a nice family. There are four people and they are Mr. White, Mrs. White, John and Kate. The key is Mr. White's. Mrs. White found it under Kate's dictionary this morning and she put it in me.

The eraser is John's. Kate found it in her schoolbag and put it in me. What about the pencil? Well, it's John's, too. Mr. White found it next to his computer this afternoon and he put it in me.

Is there a Lost and Found box in your family, too?
