Barto, my mom moved to Texas. She has echoed that the people are incredibly hospitable. They know where she works that her family is in Michigan. They take her out and do things. Even so much as "forcing her" to go out when she doesn't feel like it.
It's a weird thing. From the philosophical standpoint I think Texans are genuine assholes. From the practical side, those same people that I think epitomize what's wrong with America would often be the first to pull over on the highway to help you change your tire.
Alas, I think that hospitality is diminishing. It's really more of a rural thing, and with increased urbanization, you get more douchebags. Still, when I travel inside of this country it's pretty stark just how much friendlier we tend to be than everybody else. Hell, I tried to break my habit (unsuccessful) of holding doors open for people in NYC because I got tired of being looked at like I was a tard.
