When I was walking down the street one day, I found a small bag on the ground. I picked it up and opened it to see if I could find out the owner’s name. There was nothing inside it except some dollars and an old photo--- a picture of a woman and a young girl about twelve years old. I put the photo back and took the bag to the police station. Before I left, the policeman wrote down my name and address. He thought the owner might want to thank me.

That evening I went to have dinner with my aunt and uncle. They had also asked a young woman to have dinner with us. Her face was familiar, but I couldn’t remember where I had seen her. During our talk, the young woman happened to say that she had lost her bag that afternoon. At once I remembered where I had seen her. She was the young girl in the photo, though she was now much older. She was very surprised, of course, when I told her about the bag.

After dinner we went to the police station and she got back her bag. The policeman said to me, “It’s a wonderful thing. You not only found the bag, but also the owner of the bag.”
