At mid-point during a game, the coach calls one of his 7-year-old hockey players aside to talk with him.
The coach asks, "Do you understand what cooperation is, and what a team is?" The little boy replies, "Yes."
"Do you also understand that what matters is not whether we win or lose, but how we play together as a team?" The little boy nods his head.
"So," the coach continues, "I'm sure you know, when a penalty is called, you shouldn't argue, curse, or attack the referee. Do you understand all that?" Again the little boy nods his head yes.
"And when I call you off the ice so that another teammate gets a chance to play, it's not good sportsmanship to call your coach a jackass, now is it?" The little boy answered, "No, sir."
"Good," said the coach, "Now please go over and explain all of that to your mother."
