Mr. Jenkins is a farmer. One day he drove his truck to town and on the way his truck knocked down a boy and hurt him. He took the boy to a hospital and he paid a lot of money for that, but the boy’s parents wanted to get more money from him, so they said their son couldn’t lift(举起) his right arm above his head.
