     Joan worked in a hospital as a nurse. One evening there was a big dance at the hospital. Most of the

doctors and nurses would be there, but it was Joan's turn to look after the sick children. She liked dancing

very much, so she felt very sorry for herself.

     She went to each sick child one after another and said good-night, until she came to one little boy,

Dickey. He was eleven years old, but he was already able to talk like an adult ( 成人). Poor Dickey had

a very serious illness, and now he was hardly able to move any part of his body except his hands. Joan

knew he would never get any better, but he was always happy and always thinking about other people

instead of about himself.

      Dickey knew that Joan loved dancing, so now when she came to say good-night to him, he greeted

her with the words, "I' m very sorry that you have to miss the dance because of us. But we are going to

have a party for you. If you look in my drawer (抽屉), you ' Il find a piece of cake. I saved it from my

supper today, so it' s quite fresh. And there is also a dollar there, You can buy something to drink with

that. And I' d get up and dance with you myself if I was able to," he added.

      Suddenly the hospital dance seemed very far away and not at all important to Joan.
