“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.”

Billy’s dream came true. He lived three months longer.
