I have had other moms tell me at ballgames how their husbands will critique the games all the way home, fussing at the kid for messing up a play, telling them what they should have done - with the kid ending up in tears. One mother told me she drove a seperate car just so she wouldn't have to listen to it.
The worst thing I've seen is a 10 year old trying to pitch wiht their daddy standing on the side lines yelling at them. How awful to do that to a child and I would hate to be in that home when the boy begins to grow into a man and realizes he doesn't have to take it. (Bye-bye baseball)
I forgot to add that the little ten year old pitcher was beginning to cry and trying hard not too. His father was the assistant coach so he wasn't going to be pulled.
I have seen some of the best men I've ever known coach youth sports but then all it takes is a few know-it-alls to ruin it for everyone, especially the kids.
