Anyone remember this story?
That is one thing I have really appreciated about almost all our kids' coaches, when they were involved in minor sports, particularly when my son played football in high school. Their coaches really set the tone on everything and they absolutely would not abide poor behaviour from anyone associated with the team, playing on it, or from the parents in the stands. It was always made abundantly clear at the beginning of the season, that parent hectoring in any fashion, whether it was toward the team or the guest team, was not tolerated.
