Kenny was the neighbor good friend of Rick and Joyce Taylor. Rick hepled repair Kenny's truck, and Kenny cut the grass in the Taylor's yard. One day, while the Taylors were out, Kenny began to cut the Taylors' grass. Joyce came home, saw what Kenny was doing, and made no effort to stop him. Kenny negligently ran over a patch of gravel. One piece of gravel shot through the air and struck Jackie in the eye. She sued not only Kenny, but the Taylors as well, claiming he was their agent and they were responsible for his negligent act. Was Kenny the Taylors' agent?
