| When I was walking down the street the
other day, I happened to notice a small brown leather wallet lying on the
sidewalk. 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 change and an old photograph--a
picture of a woman and a young girl about twelve years old, who looked like the
woman’s daughter. I put the photograph back and took the wallet to the police
station, where I handed it to the desk sergeant. Before I left, the sergeant
took down my name and address in case the owner might want to write and thank
me. That evening I went to have dinner with my aunt and uncle. They had also invited a young woman so that there would be four people at the table. Her face was familiar. I was quite sure that we had not met before, but I couldn’t remember where I had seen her.
