While not the stereotypical extrovert, I experience the opposite in my country.
I think, on a world wide scale, I would be considered very introverted, but by Danish standards I'm too social. I've become more introverted over time because it is too exhausting trying to get something going with people around me. Danes make all their friends in their youth and then they close the gates at 30 and never allow in any other new friendships or acquaintances ever again. And if they do, it's against their will.
We moved into a new neighborhood five months ago, and I still don't know anyone. Our closest neighbors have politely demonstrated that they desire to not know me despite my attempts at getting to know them and I am self aware enough to know when to just let it go and avoid thing becoming uncomfortable.
It really sucks, because I always dreamed of having good relationships with my neighbors and inviting people over for cook outs or something. But Danes are hermit crabs.
I had it confirmed when I befriended a Ukrainian refugee who told me that in the two years he had been a refugee in Denmark, I had literally been the only Dane to bother to get to know him and been friendly and open to him. Told him that I'm also a very shitty Dane.
So yeah, I dunno what it's like to be an introvert stuck in an extrovert society. But I do know what it's like to be extroverted introvert in a hyper introverted society and that sucks as well, because you end up becoming very, very lonely if you don't hit the jackpot with evergreen friendships when you still have your milk teeth.
