This is pretty on the nose for me. My wife and I moved from a Chicago suburb to Portland about 5 years ago. The amount of effort required just to strike up a convo with strangers (and keep it going) was pretty significant. We especially missed how acceptable giving people "the business" (i.e. harmless joking or razzing to lower someone's guard and make them feel comfortable) was so common where we grew up. You could give someone sh*t for something trivial then end up helping them remodel their basement.
It was isolating for a while until we sort of gave up and accepted that people are just different out here. There's nothing wrong with that, but we're moving back to Chicago (for other reasons). We're looking forward to not having to jump through hoops just to have a meaningful convo with a stranger again.
