Parents started a long time ago telling kids they were perfect and that they could be anything they wanted to be. That is simply not true. Some kids learn around junior high kids are mean as hell to each other and everyone can not be whatever they to want to be. But some do not learn this until they are adults, and they are bitter and mad for not getting what they are "entitled" to. My day you got in trouble in school, you got worse at home. Parents did not bitch to teachers or the school for disciplining kids. Matter of fact, most of my friends parents would discipline any friend that came over to visit their child and was out of line. Parents were ok with that. Bad behavior was seldom overlooked and was met with immediate consequences. If you did not get discipline at home you got at school, and again the parents was ok with that. So, if you wanted to mean jerk you were really needed to do it without adult supervision at home, the class room, or church. And if you were a jerk and some parents called yours, you were in trouble.
If you sucked at baseball or any sport in my day you did not get to play just because you were on the team, you got in near run rule territory. But they made scrimmage work easier, and they kept the starters on their toes, their was a great value and even a hero type view of the kids that simply stuck it out for the love of the game and supporting the team. Finish what you start, give yourself up to a goal that is bigger than your personal achievement.
Dad, mom, players, and Coach was not mean to these kids, at least we were not. They usually just wanted to be a part of the gang and we treated the bench players well, they were our best cheerleaders. In HS we had a guy that loved football, classic skinny kid old school super "nerd", black coke bottle glasses, was legally blind. Could not get a DL because he was so blind. He was a trainer and equipment manager, we treated him like he was our MVP. Anyone picked on him at school, it was a big mistake, we had his back. Today he is rich Doctor. We made sure he got a good date to the Senior Prom.
But the other key thing was, it was OK to not be a great baseball player. It was OK to try do your best and learn from "failure" and deal with it at a young age and not 30 years old in mom's basement. It was OK, to be encouraged maybe you leave baseball and find something you ARE better at, to find your god given talent, we all have something to offer, some gift, you have to be lucky to have parents that help you find it and not force their kids to be what they want to be.
Maybe that kid at the end of the bench finds out he is great at rowing, or maybe can play a musical instrument really well. We had a guy that dropped out of sports and loved being magician, does it on paid basis to do this day. Not nationally known, but he found his gift that excites him and people are attracted to .
You didn't have dad and mom lying to their kid telling them how great they are and they should be playing and the Coach knows nothing. Or that their child is a straight A student and the teachers are all failing. Learning acceptance and accountability at young age does not happen. Parents are teaching you, you are a victim. You are great, you can be anything you want to be. When the lie hits him I am sure it is a very harsh dose of reality for some. We are born equal as human beings, we are not born equal in mental and physical god given ability.
