One autumn afternoon, my mother asked me to go to the store and buy some vegetables. I gladly agreed. The weather was warm, I liked the walk. On the way to the store, I noticed a man who made his way into the house across the street through the window. I called the police. A few minutes later I saw a police car and two policemen entered the house. Soon the policemen left the house and approached me. I felt excited and proud of myself. But the police looked angry and accused me of wasting police time. It turned out that the man had lost his keys and was forced to enter the house through the window. I felt so bad. I apologized to the police and the man for my stupidity.
