Last week I went to a movie, which was very moved. It was a sad movie about a mother and her sons. When the child was a little boy, his mother was very poor that she had to send him to rich family who had no child. The boy received a very good education and twenty years late became a doctor. In his hospital, he had a patient, who was an old lady. He didn’t care too much of her, for she could hardly afford the medical care. One evening, the lady died quietly of a serious illness but on her bed, the doctor found a letter, in it he discovered the truth that she was his mother. He had wanted to call her mother, but it was too late.
