Some coaches are weak regarding their ability to communicate and show respect for players. The first time the coach showed up my son I was livid. I stood quietly on the sidelines with smoke coming out if my ears and blood coming from my eyes. I said nothing but "no comment" to anyone who commented about the situation.
After seeing it happen to other kids, the second time it happened to my son I shrugged and told people life goes on. The second time was when blood should have been coming from my ears and eyes. The coach criticized my son in the newspaper for not having the year he had junior year. He was coming back from surgery when he was supposed to miss the season. He was hitting over .400 with less power.
As you can see there are some things you don't forget. But you keep your mouth shut and roll with it.
