Older people grew up socializing constantly so they can just start talking to strangers like they've known each other for years, especially if they are from the same town.
I volunteered at an old folks home from age 10-16 or so, this was back in early/mid 90s - before the Internet stole my attention - and the old people were of the Greatest Generation cohort (maybe some of the oldest from 1800s). I really enjoyed those talks and have always liked talking with old people since. I can sit with any of them and just talk for hours but rarely ever do this with younger/my aged people. They just chit chat about everything and silence is never awkward, they could talk about anything from the weather to big social/political issues with an open mind. Unfortunately, I fear this is ending soon as this latest generation of old people is kind of vile and not really seeking positive conversation (wild generalization but it's my experience). Instead they tend to want to tell you how to live, what to believe, who to vote for, etc. and then judge/ridicule you when you don't comply or voice a differing opinion.
FWIW, I also think it's largely because boomer's collectively lost their minds and started acting out when their parent/grandparent generation was gone. It's like they didn't want to disappoint them so were acting on good behavior, but now their true colors show.
When my dad does this it’s mortifying
When I do it though it’s very cool and fun!
Of course I don’t call women “girl” or try to order in languages I don’t speak
Someone commented once about the Trader Joe’s people always flirting with everyone, and a) that’s probably true but b) is just being nice to random people these days so intimate and invasive that it’s equivalent to getting hit on? That would explain people cringing
