Yes I agree. They were not talking to me. They didn't know who I was. I just happen to be behind them when they met up to walk to the parking lot.
When I go to a game I socialize withteam parents befor the game and when not videoing I sit with the opposition parents. We get teams from all over the US and Canada to our tournaments. I find that interesting. I usually don't tell them if my son is pitching. I just talk baseball. I don't react to my son's games anymore. I can't even sit with my wife. She gets too excited.
I also sit with UMPs a lot who I have known for years and Like most of them a lot. We discuss strike zones and all the issues with umpiring and have no problem with them. Some are fantastic with kids and feel they have a role in their development. I give them a lot of respect and my son does the same.
