     Last week I went to a movie. It was very touched. It was a sad movie about a mother and

his son. When the child was a little boy, his mother was very poor that she had to send him to

a rich family who had no child. The boy accepted a very good education and twenty years late

became a doctor. In his hospital, he had a patient, who was an old lady. He did care too much

about her, for she could hardly afford for the medical care. One evening, the lady died quietly

of serious disease and on her bed the doctor found a letter, from it he discovered the truth and

felt the love of a great mother. He wanted to call her mother, but it was too late. Nobody in the

theatre was moved to tears.
