Yes, fully agree with the MH aspects.
Everyone was friendlier back then too. Shop assistants and receptionists (well everyone really) would make eye contact and actually speak rather than grunt at you as if you're a nuisance. There were fewer introverts - interacting with other humans was the norm, not like today with so many people shuffling around trying to pretend you're not there, wearing headphones, sitting (hiding) in corners, etc.
I think we're losing the ability to interact with random strangers, small talk, etc. That's because youngsters aren't "playing out" anymore, so don't get the same breadth of human contact, i.e. the old days of there always being a game of footie on a nearby patch of grass that was truly "everyone welcome" where you just joined in, even with kids you didn't know.
There are so many threads on here and other fora about Uni students who are lonely, depressed, etc., as they think "everyone else" is having a good time except them - they're just not used to going out and joining in! Unis are the one place where there's so many choices, lots going on, etc., but it's down to the student to get out there and join in. Whenever I go to our local one, it's like a zombie city, with loads of people randomly wandering around on their own, headphones on, eyes down - it's such a shame compared to how it used to be when it was friendly and vibrant.
The real killer for the internet for me is that I know quite a few people both online and in real life, not particularly "friends" as such, and they have completely different personalities. On line, they're constantly writing and responding to posts on SM, in real life, they're "head down, earphones in" not making contact! One sits a few seats away at our local football club - he writes blogs about the game on his own website, records his own webcam "chat" videos about past and upcoming games, but in real life, he's literally mute - it's so strange as everyone knows him from his website where he's friendly and chatty, but at the game he just won't interact with anyone. As part of his webpage, he also chats about other things, and he keeps mentioning his depression, anxiety, etc - I'm sure if he had a few "real life" friends rather than hiding behind the internet, he'd be less depressed!
