I'm sorry but I disagree. Here's the thing, everything you're saying is true in the context of a big city. However, you come out to the country and none of what you're saying holds true. I've lived in Chicago and I've lived in Iowa for years each. I had lots of friends in both places. I talk to exactly one person from Chicago still, but I regularly keep in touch with all of my Iowan friends even after they've moved.
Yeah I lived in a small town in Midwest and then in big cities. But maybe I never experienced try truly rural US (as in you have to drive 40 miles to do grocery shopping).
I am sort of afraid that the last point holds for me and I just got paranoid and old and people don't want to be friend with me. To me, it might seem like it is a old-world vs US or other such things, but it could be just me rationalizing all along. That is why I am interested in getting others perspective on this.
