At one of my U12 games this spring, one of the other team’s parents was bellowing loudly (that’s the only adverb I choose to use) the entire game. I heard him loud and clear the whole game, which I rarely do of the spectators on the other sideline.
A couple of my kids expressed relief that it wasn’t their dad. Another of them said he hoped the guy would keep doing it. Puzzled, I asked why. He said it was good because the dad was distracting the other team’s players.
