My Brother's Kid

The coach called my 12-year-old nephew Travis to the side and asked, “Son, do you understand what cooperation is, And what a team is?”
Travis nodded.
“Do you understand that what matters most is whether we win or lose together as a team?”
My brother's son nodded, yes.
“So,” the coach continued, “I'm sure you know, when a play is called, you shouldn't argue, swear or call the ref a 'dickhead'. Do you understand all that?”
Again Travis nodded.
He continued, “And when I take you out so another boy gets a chance to play, it's not good sportsmanship to call your coach 'a useless twat' now is it?”
Looking slightly ashamed by now, Ken's son agreed.
“Good,” said the coach. “Now go over there and explain all that to your Dad”
