The six-year-old Billy was seriously ill.
“Billy, what do you wish to do in the future?”
“Mom, I always want to be a fireman.”
His mom went to a fire station. She told a fireman about her son. She asked if it might be possible to give him a ride in a fire engine（消防车）. The fireman said, “We can do better. We’ll  make him an honorary（名誉的）fireman for the whole day. He can come to the fire station, eat with us and go out on all the fire calls. If you give us his sizes, we’ll get a real fire uniform for him.”
Three days later, that fireman dressed Billy in his fire uniform and drove him to the fire station. Billy was so excited. There were three fire calls that day. Billy rode in different fire engines and went out all the three calls.
Billy’s dream came true. He lived three months longer.
