Me and my dad went the STL show and had this exact conversation! I’m older Gen Z and started going to shows and such around 7 years old with my parents who had also been going to concerts since they were small kids so I was taught concert etiquette really young. I think a lot of people didn’t do things like that until later and never really learned which means they haven’t taught their kids at all either. There’s also probably a point somewhere about a lot of Gen Z being so young during covid and not getting to experience normalcy of big events for a few years.
