Like said, in the central and northern parts of Sweden, people are known for being rather “mute”. Is there any such place in/part of America?
In Gothenburg, where I live, people in general are quite the opposite. If you're the social type of person, It's hardly a place that will make you cry out of isolation and loneliness. In fact, to talk a lot, “tjôta” (don't try and pronounce it), is a sort of cultural institution in my city. Maybe it has to do with the fact that we are a large port city and that the places of work in Gbg typically are assembly lines, harbor environments and such places where people are dependent on each other and on communicating even if everyone doesn't know everyone else.
I've noted the same differences between different parts of a country when traveling abroad. For instance, in Florence, Italy, people are polite, yet very reserved. In Rome and especially in Naples people are completely different. In one way it's a bit amusing, but sometimes it's annoying when strangers intrude on your privacy.

Yes, in a way, people in the Washington DC metro area often exhibit a kind of social “shyness” or “coldness” that I haven’t noticed so much in other areas of the USA, especially not in the American South.
For example, if you’re pushing your cart down a grocery store aisle in metro DC and make eye contact with a shopper coming from the opposite direction, that other person will normally avert his/her glance and pretend not to see you.
But in the American South, when you make eye contact in a grocery aisle, the other shopper usually will smile and even voice a soft “hey” — or perhaps a big “howdy” in Texas!
(Note: American Southerners, at least those from the older generations, generally don’t say “hi” to greet one another. They leave that expression to Yankees.)
