                                             Are You Still Looking for Your Son?

      Mrs. White has a son. His name is Sam White. The young man begins to work in a post office in

a city this Autumn. He asks his mother to visit the city. The old woman is happy and catches a train.

She soon arrives in the city, but she doesn't know where the post office is. She begins to look for it,

but she can't find it. At a bus stop she asks an old man, "Excuse me, sir. How can I get to the post

office?" 

      "There are about forty post offices in our city," says the old man."Which one do you want to find?"

      The old woman gives Sam's letter to him and the old man says, "Walk along this street and take the

fourth turning on the left. His post office is just there."

       Mrs. White thanks the old man and soon finds her son. They are very happy. A week later the

woman goes to the zoo. She sees all kinds of animals. But she can't remember the way back to the post

office. At the same bus stop she meets the same old man and she asks the same question again.

      "Oh dear!" the old man says. "Are you still looking for your son?"
