     A girl became a volunteer in the activities of Deathbed Care, which meant visiting and taking care of

a patient suffering from an incurable disease with days numbered.

    The girl was assigned to look after an old man suffering from cancer whose children lived abroad.

Their living conditions were not satisfactory while the old man had a lot of savings. She was expected to

comfort him and keep up his spirits.

     Every Saturday the girl came on time to keep him company, telling him stories.  When he was having

an intravenous drip (静脉滴注), she would help massage his arms. The doctor found the patient much

improved mentally. The old man began to involve himself actively in the medical treatment and he seldom

shouted at others.

     But something that happened made the doctor uneasy and puzzled. Each time the girl left, the old

man would give her some money. The doctor did nothing to interfere (干涉), unwilling to offend the old

man.  A month later the old man showed evident signs of decline after suffering coma (昏迷) a few times.

     When rescued from the latest coma, the old man told the doctor his last wish, "I have deep sympathy

for the girl. Will you be kind enough to help her finish her studies?"    

     But the doctor knew that her family was welloff and she had no difficulty pursuing her studies.  

Sometimes she even came to the hospital in her father's car.

     When the girl came at the weekend after the death of the old man, the doctor told her the bad news.

She was very sad and burst into tears. Then she handed  $ 500 to the doctor, saying, "The old man had

all along thought I came to do the job because of poverty. He gave me money so that I could continue

my schooling." Now he got the answer to the puzzle. In the last period of his life, the old man found it a
