Mrs. White has a son. His name is Sam. The young man begins to work in a post office in a big city this autumn. He asks his mother to visit the city. The old woman is happy and catches a train. Soon she gets to the city, but she doesn' t know where the post office is. She begins to look for it. At a bus stop she asks an old man, " Excuse me, sir. How can I get to the post office, please? "
" We have about forty post offices in our city, " says the old man. " Which one do you want? "
The old woman gives Sam' s address 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' re very happy. A week later the old woman goes to the zoo. She sees all kinds of animals. But after that she can' t find the way again. At the same bus stop she meets the same old man and she asks the same question again.
" Oh dear!" the old man calls out. " Are you still looking for your son? "
