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