If you've coached high school sports for at least a season or two you surely have been subjected to at least one crazy parent that takes more of your time and energy than all the other parents combined. I had one crazy mom (worst I've ever experienced) graduate last year and a new crazy mom popped up to fill that spot this season. So far it has only been parents of boys that are either the fastest, second fastest or third fastest on the team. No exceptions with that despite coaching the girls and boys with a team of about 100 kids total.
I'd be interested to hear your more outrageous episodes.
