I spent several years living in Mississippi. As someone who was fairly introverted upon arriving in the Deep South, I had that hammered out me pretty quickly, during every opportunity for social interaction. It's just part of the culture to engage. I think my time in that area was a bit of a mixed bag, but that one change was for the better, and it has led to wealth of relationships since. Most people yearn for some bit of connection, and it's not that difficult to be the catalyst.
