Yesterday when I was walking along the street, I saw an old lady in front of me. She wanted to cross the street. All of a sudden. a bicycle ran against her at a high speed. The old woman fell to the ground. The cyclist was very frightened and ran away. I hurried to help the lady up, called a taxi and sent her to the nearest hospital. Luckily she was not badly hurt.
We live in a large city which is like a big family. We should care for each other.
