My friend Tony and I always walk home together after school. Last Friday on our way to home, we heard a loud shout behind us. When we looked around to see what had happened, we found a woman lied on the ground, bleeding. We soon realized that she had knocked down by the car in front of him. We hurried to help her, and a man came over and tried to prevent us from getting closer to the wounded woman. We got very angrily with the man. How could he stopped us from helping a dying woman? The man asked us to turn around and we were surprised to see a man who were carrying a video camera on his shoulders. In fact, they were just shooting a film!
