Well good for you liking meeting people, are we preventing you somehow?
I dont think enough of us have commented on this thread for you to extrapolate that people are becoming more and more introverted, I've always been introverted.
Most of us cannot in fact hide away, we have jobs, the shopping to do, the limited but necessary events to attend, even sometimes see the neighbours.
Even if we managed to wfh, do all shopping online and never ever attend any events, you still get sick and must meet drs, others in the waiting room, get your eyes checked, see the dentist, take your pet to the vets, take your children and/or parents to many appointments, walk your dogs, pay the milkman, see the window cleaner and more.
I dont mind negative interactions, but people get mighty pissed off when I say what I really think. And menopause makes it way easier to say what I think.
I dont have any opinion on other people, I'm just perfectly happy with my own company. I dont need extraneous people, I'm perfectly fine as I am. I'm not depressed or anxious, I just prefer my own company.
If i suddenly decided i needed someone with me right now, I'd go to the pub for today, if I decided I needed people longer term, I'd find a club to join. It's not like I decide now to be a loner and forever more I must be a loner. I can (but wont) change my mind.
