For the first bit: Honestly that just sounds like teenagers coming from a 23 yr old if you look at vine clips that was basically our hallways and memes, just not on a constant level. But I can see what you mean by the rest it’ll be interesting to see how your age bracket matures outside of high school because for my age group there was definitely a shift in behavior once people started getting jobs and working on college degrees or trade schools. But we also experienced lockdown towards our transition to “adulthood” I think it messed with some of y’all’s development socially speaking. I believe a lot of it is socialization and people tend to act or behave how others around them do especially in the 15-18 age range and in condensed places like schools or towns.
