Every Saturday, Mrs. Smith goes to the shops. Last Saturday she did the shopping and began to walk to the bus stop. The bus stop was at the end of the road. Her bag was heavy and she had to have a short rest. She stopped beside a new car. It was parked at the side of the road. When she stood there, she saw a police officer coming to her.“Excuse me, madam,”said the police officer,“I want to ask you some questions. What's your name?”“Jane Smith,”she answered,“but ...”“And what is your address?”he asked again.“36 Marbet Street,”she said,“but I don't understand why you are asking these questions.”“Can you read the sign there, Madam?”asked the police officer.“Yes, I can,”said Mrs. Smith.“It says'No Parking'.”“Yes, Madam. But why did you park your car there?”“But it's not my car!”said Mrs. Smith.“Isn't it?”said the police officer and his face turned red.“I am very sorry ...”he said to the woman. Before he finished, another woman came. She kissed the police officer and said,“Hello, dear! I knew I could find you here. Happy birthday! I bring your birthday girl.”“Thank you, dear, but where is it?”“Here it is!”his wife said, pointing at the red car.
