A few words from the coach

At one point during a game, the coach called one of his 9-year-old baseball players aside and asked, "Do you understand what cooperation is? What a team is?"

The little boy nodded in the affirmative.

"Do you understand that what matters is whether we win or lose together as a team?"

The little boy nodded yes.

"So," the coach continued, "I'm sure you know, when an out is called, you shouldn't argue, curse, attack the umpire, or call him a d***-head. Do you understand all that?"

Again the little boy nodded.

He continued, "And when I take you out of the game so another boy gets a chance to play, it's not good sportsmanship to call your coach 'a dumb a**hole' is it?"

Again the little boy nodded.

"Good," said the coach.

Spoiler:

"Now go over there and explain all that to your grandfather".
