Last week,I was walking along the street. I saw an old woman standing in front of me. She was about to cross the street, suddenly when a car appeared, which was drived so fast that hit the old woman. But it didnt stop. I quickly helped the driver take her to the nearest hospital. Fortunately, the old woman didnt hurt her legs and feet. Now she feels better, and her children are taking care of her. My mother would always tell me that I should be careful before. However, I didnt listen. After this accident, I become really careful.
