As a quasi-forty-year-old dude, it's weird to be caught amidst this shift... I mean, until now, 2/3 of my life has passed without internet and social medias; it'll eventually turn around as I get older, but the worst feeling is knowing how cooler life was before internet and knowing it won't go back to that state is kinda disheartening-- not saying internet is bad, just saying internet is taking the best out of us (humans) in terms of social interactions.
So, answering to your question: How Does Anyone Meet Anyone These Days?
I have no fucking idea!
We used to meet ppl anywhere, parties, free festivals, through friends of friends of friends. One of my best friends is one of those we meet through others at a drunken night out.
