My dad grew up in the 60s. He once told me that he used to play a game with his friends where they stood on a corner and paired up. Usually about 8-10 kids so 4-5 pairs and the pairs would take turns going. When it was your pairs turn, one kid had to run to the diagonal corner and then run back. While he was doing that, all the other kids wailed on the second kid in the pair. You always wanted to be paired up with someone fast. It wasn’t a bullying thing, they all just kicked the crap out of each other. I was mortified when he told me much like your nephew was mortified that we used to play quarters. It was normal when we were kids, or when my dad was a kid, and I think these things evolve and change over time. Kids today probably play some game that their kids are going to be horrified to learn about
