You took the words out of my mouth. These games really do mean nothing. I've got one kid that's DA, the other is in the lowest league in town. They both want to win, but they also both move on with their lives right after the game as do their teammates.
If you are a parent and you are this vested in the outcome of their game you are ruining it for them. Read the thread about parents whose kids have quit. I guarantee some of those kids stopped playing because Mom and/or Dad cared more about it than them, put too much pressure on them and/or embarrassed them with their behavior. If you say anything, say "I loved watching you play" and let them succeed or fail on their own. Yelling at a ref or critiquing their game isn't supporting them.
This!
My son has been on teams with parents who care more about the outcomes of games than their kids' wellbeing. We had a game in Lancaster early on where the reffing was bad and the other team played kick ball and we got our butts handed to us and the parents (most of whom had never played soccer) surrounded our coach after the game demanding answers as to why we didn't boot the ball up to our star striker and blah, blah, blah. During this very serious parent meeting, the kids were over by the bathrooms playing "three flags up" and having a blast. The game was already in the past for them. It was the parents that were teaching the kids to cling to bad outcomes. The kids didn't give a sh--.
Another example, also early on. We played a team that - some parents suspected - had an over-age player. A few days later, some of the parents got together to see what they could do to lodge a protest. One of the other parent's kids asked what they were talking about. His dad went into a long thing, "you remember that huge kid that ran over everyone and scored all those goals...? We think he may be too old, blah, blah, blah." The kid was like, "Which game was that again?" The kids don't give a sh--.
And they shouldn't.
I know it's hard to resist getting caught up in "fan culture" because that's how our parents were (usually), but the more my son plays and the better he does, the more clear it is to me that the outcomes of these games do not matter at all. What matters is what you learn while playing.
