That's a good point re introversion. I am 100% an introvert, but I am neither shy nor socially awkward. If I tell people I'm an introvert, they express disbelief.
And I also agree with the PP who made a comment about it being a backlash against extroversion dominating for so long. My one extrovert friend is so accustomed to social=fun/normal that she thinks anyone who isn't like this has something wrong with them. She is suffering, because without the compelled frivolity, she has nothing to do. She has spent her whole life socialising meaning she has no hobbies or ability to keep herself occupied.
I suspect the tide will turn again if we find it affects businesses, and the implicit shaming of introverts will resume (along the lines of the PP referencing 'Brenda' below ).
Re Brenda below (being pathetic and doing puzzles 🙄) I've noticed that if my time is occupied doing something that is considered worthwhile by others, then my time alone doing it is respected. However, if I spend a long time revelling in the joy of knitting, for example, my time alone is judged.
But the fact is, knitting does so much more for me than sitting with a group of people who probably don't have hobbies and gab over cups of tea as a way to whittle away their time (as is the case with a group I used to feel pressured to join). I develop new skills, end up with an actual product and have a sense of achievement. The others can dress their group up as friendship, but I honestly think it's just sustained by individuals who are very very bored.
