I went shopping with my wife. We have a lot of things to buy. We drove to the center of the city and stopped our car in the front of the shop. An hour late, we came back to the car. But it was strange that we couldn’t open the door. So we asked policeman for help. It was glad to help us. A few minute later, he got the door open. Just then a man came up and shouted angrily. ‘How are you doing with my car?’ We were surprising and went to see the number of the car. What you think we did then? We had to speak sorry to the man again and again.
