I grew up in a small Texas town, lived 20 years in Austin, then fled back to small-town life 15 years ago. So howdy and welcome! You've gotten some great advice on making friends and such so far. I only have a couple minor bits to add.
When I first returned to small town life, everyday things seemed to go much more slowly -- checking out at the grocery store, going to pay a bill or renew something governmental, for example. And "visiting" was often the reason why. The clerk would visit (chat) with the person in front of me while the transaction went on and for a few moments once it was done, which is jarringly different from what I was used to in the city. What I had to make myself remember was that I was feeling impatient in a "line" that consisted of two whole people. That line would've been much longer in the city, and there would've been little or no small talk. And I love me some small talk!
The other thing is what I call "The Glide." When you are driving on a quiet, rural, two-lane blacktop and a car is (at long last) oncoming, more often than not, it will slowly glide to the far right of its lane, rather than stay centered in the lane. I've always taken this as a message -- "I see you up ahead, I am awake and paying attention, no need to worry, I got this." Once the two vehicles pass, they both return to the center of their respective lanes. The glide is comforting, to me. It lets me know that, hey, this driver isn't gonna zone out and cross into my lane on a road with little or no wiggle room.
Hope this makes some sort of sense. And again, welcome to the boonies!
