I was shopping with my wife and we have plenty of things to buy. We drove to the centre of the city but stopped our car in front of a shop. An hour later, we came back to the car. But it was strange that we could open the doors. So we asked the policeman for help. He was glad to help us. a few minutes later, he got the door open. Just then a man came up and shouted angry, “What are you doing with my car?” We were surprising and went to see the number of the car. It was not his. We were very embarrassed on that time. What do you think that we did then? We had to speak sorry to the man.
