Its just a game

Emma's soccer season has started and so far she has played 2 games. She loves playing and really looks forward to each game, wanting to do well but above all to have fun. Usually she achieves this. However earlier this week the two coaches had a disagreement at the end of the game and were shouting at each other. This really put a damper on the kids excitement, and in my opinion, is totally inappropriate. This is the first example we've seen of over-competitive parents at sports event and it was unpleasant. These are 8 and 9 year old girls, they enjoy playing and the aim should be to encourage them, help them develop their skills, get some exercise and have fun. What kind of message are the coaches sending to their teams if they scream at each other because they did not like the way the game went?
