They avoid empty niceness
"Vermonters are not only charmless of manner, on the whole; they are also, as far as I can judge, utterly without pretense, and give the salutary impression that they don't care ten cents whether you are amused, affronted, intrigued, or bored stiff by them. Hardly anybody asked me how I liked Vermont. Not a soul said 'Have a nice day!'"
-- Jan Morris, British writer
