I've caught myself getting more upset than I should at times at the coach or ref. But I've grown up. I've learned to relax and let them play. It's not all about winning. Parents need to lighten up and remember kids are there to have fun.
Nothing's worse than a dad or mom in the stands screaming and swearing.
A lot of us parents were horrified. It was awful. It's coaches like that you don't want your kids coming in contact with. The kid just dies out there on the ice of mortal embarrassment. I've not been a perfect parent.
