I happened to be near a park once where I saw what appeared to be big Mexican party. Lots of people drinking, loud Spanish music etc.
They strung up some Pinata and had blinded folded this kid and handed him a bat. First swing he impacted the side of another kids head who happened to be standing too close. The sound of the impact was ugly. He dropped to the ground.
The party became very hysterical. I saw several carrying the kid, stumbling and running with the kid who appeared unconscious, to a pick up truck. The truck sped off...
I saw the same thing. A kid in my sons Cub Scout pack whacked the heck out of another kid. He didn’t mean to, just an accident but it kind of spoiled the party.
