I keep thinking this same thing myself, and have tried to work the IRL-angle, but when you're an adult no one really wants to meet you.
Up until the early 00s, I used to hang out at a coffee/cigarette bar where I knew just about every single person who walked through the door, and people would sit there for hours and hours talking to strangers about very interesting stuff, while drinking insane amounts of coffee and chain smoking.
If those sorts of places still exist, I have no idea where they are.
