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．”
