the sad thing I see at most every game is the coaches stalling around on the field after the game before they can leave, as they are clearly waiting for the parents to leave the stands so they don't have to face the "barage".
I had to put an end to my coaching days a few years ago. I don't miss- the mom who told me her 10 year old was already being recruited by UCLA; the dad who complained about the number on his son's uni and that the uni's weren't "fancy" enough; routinely waiting in the park for over an hour until the last kid got picked up; taking home the kid who's ride never came.......
Never had a problem with any kid and when one of your players comes up to you and says thanks and when I run into former players now grown up, in college etc. and they just say "hey coach, how are you doing", it was all worth it.
