Right then Grandpa decided to learn something new. My brother JOHN knows how to golf so they go together. The meaning of JOHN is stand. He can't let Grandpa run all over him. Otherwise he would only be a caddy and never get a chance to play the beloved sport.
Grandpa hits the ball.
Then he yells some nonsense. John looks up and gets hit. It is inevitable. It seems to happen everytime they play. John informs him as pluck, he gets hit in the head.
