One day,I had to go far away from my house for work.I decided to go there by train.I left home early that morning.When I was on my way to the train station,I saw an old woman,with short white hair and a walking stick.It seemed that it was very difficult for her to walk for too long.Suddenly,a man who was riding a motorbike ran quickly through the street.The motorbike hit the old woman and knocked her down.But the man didn't stop his motorbike to help the old woman.Instead,he went away.I was a good man.I came up to the old woman ,with saying "Are you ok?".Fortunately,she wasn't hurt seriously.Soon I dialed 120 and took her to the hospital.At last,I missed the train.Although I missed the train,I felt very happy,for I did a good deed .
