     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 of course somebody had to be left to look after the sick children,

and Joan was not of the lucky ones. She liked dancing very much, so when she had to start work that

evening while her friends were getting ready to go to the dance, 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, Dick.

He was eleven years old, but he was already able to talk like an adult. Poor Dick 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 himself.

     Dick knew that Joan loved dancing. So 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, you find a piece of cake. I saved it from my dinner today, so it is quite

fresh. And there is also a dollar there. You can buy something to drink with that. And I'll 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.
