Settle down.
The worst thing a parent can experience is the illness or death of their child. The kids' suffering is hard for the average person to imagine and is enough to make many people lose their religion. I hope the kids got at least small lift out of the visit from the nutty coach, and the players received a life lesson that whatever they face in school, in practice, life in general they should remember how hard these little guys and their families are fighting. Experiences like that can help gain perspective about life and not sweating the small stuff. And it's all small stuff.
