Dick was a twenty-year-old man. His father was a teacher and taught chemistry in a middle school and
his mother worked in a shop. They lived a happy life until his parents died one night when there was an
earthquake (地震). Luckily his sister had taken him to see their aunt in the city and they were not at home.
Everything was destroyed in the earthquake and the two children got into trouble. Thanks to their aunt, who
was not rich, they grew up but they lived a hard life. Dick's sister was so sad that she became a nun (修女).
After Dick finished middle school, he found a job in a hotel and began to work there.
     One day the young man fell to the ground while he was cleaning a window on the second floor. He was
sent to the hospital and the doctor looked him over. One of his legs was broken and he had to stay in hospital.
He said to the nurse, "I'm a poor man, madam. Arrange a third-class ward for me, please."
     "Can't any body help you?" she asked. 
     "No, madam," answered Dick. "I have only a sister. She's a nun and she's poor, too."
     "I don't think so," the nurse said angrily. "Nuns usually marry God. And God is the richest person in the
world, you know!"
     "Well, then," Dick said with a smile, "Please arrange a first-class ward for me and send the bill to my
brother-in-law (姐夫)."
