I love loser parents bashing 9 and 10 year old teams. It's classic. Pull up your lawn chairs and have some more donuts. Living through your son will probably end poorly for both of you.
Who cares how the game ended and by how much. Did the kids get a little better? Were they happy with their red ticket for a free hot dog, or were you too busy lecturing them on the ground ball they missed?
Get a grip - it's 4th grade. Some of these teams have barely practiced!
