One day I was walking home after school while an old man fell heavily onto the snow-covered road. There were several people pass by at that time and no one took any action. Some of them said that it was none of their business; others people worried that if they helped him they might get into a difficult situation. Seeing what had happened I called 120 immediately. While waiting the ambulance I took down my coat to keep the old man warm. In no time did the ambulance came. Having helped the doctors carry him into an ambulance I felt relieved. In my opinion this is our duty to help those who are in troubles. Only in this way can we live in a great society.
