It was the attitude of a grandparent...

...who had a granddaughter that was on the team of my daughter when she was right around 8 that convinced me that softball wasn't going to happen anymore. My daughter fielded a ball in the infield and didn't quickly make the right play and this grandmother yelled at her at the top of her lungs "WHAT, ARE YOU STUPID!?!?" It was at that point that I decided my daughter wouldn't be continuing on with that softball league.

Funny thing about parents, at least from my experience, it seems they are most crazy when the kids are much younger. It seems to be the exception instead of the rule with this same daughter, who is now 16 years old, to have a parent have even much more than a quick yelp about disagreement with a call. My S12 is the other way around - there is almost always at least one parent from the other team that is boorish.
