One day morning after the snow , I saw a woman riding a bike fall off on my way to school. She was very old and she couldn't get up by herself. So I came forward to her, helping her to get up and asked for her telephone numbers of her workplace. Then I immediately call 120 and her workplace to notify the situation. Before the arrival of the ambulance, I chatted her and did a little first aid to help her stay active. Finally the ambulance came and the doctors moved her carefully into it. I said good bye to her and her smiling, I know she appreciated what i did .
What a wonderful experience I had. It felt good to help others.
