Is the high school class of 2020 stuck in high school?

I graduated high school in 2020, and almost 6 years later, what I've noticed is that at least half of the people in my graduating class are still hanging out with all of their high school friends. And I don't mean they've just kept in touch; I mean they're reminiscing how great high school was and hanging out primarily with friends from that time, even if they did make other friends in college. Comparatively fewer people from my grade fully closed that chapter of their life and moved on to something else.

The reason for this is obvious. Covid happened which caused a lot of people to either go to community for the first semester or year or take a gap year. And even if they did go away to campus, they didn't really make any friends or have any sort of an experience that would essentially bring closure to high school. So, as a result, most people ended up just defaulting to their high school friends.

I'm just curious to know how widespread this is...
