This is a thread I have to chime in on. I am originally from the heart of Appalachia, Tennessee on the Kentucky and Virginia border. My grandparents spoke a strong Appalachian dialect, and I lived with the for the first 10 years of my life. Then, when I was about to go into 6th grade, I had to go live with my parents in Ohio. It was torture. I was already shy and withdrawn, but being around all of those northern city folks made me want to be swallowed up by the ground. I had spent my life among simple people with simple ways.
We lived in what were considered slums then or now. My teacher had an attitude toward me because I don't think she believed I was really at the level I tested at. My sister felt the same way, as she had gone through the first three years of school with me in Tennessee and Kentucky, attending 2-room and 4-room schools with kids from families like ours - uneducated and backward.
Eventually, I learned to speak with a midwestern accent and still do to this day. When I went back home, however, I lapsed back into my old drawl so my friends wouldn't think I felt superior because I was "talkin' proper."
Appalachian Americans ("hillbillies") speak much more like colonial Americans. My linguistics professor in college said that it was "the purest form of the English language." A paper sack was a "poke," and sitting on my grandma's lap was being "nussed." I do not regret having the hillbilly experience in my early life. It helped me understand where food comes from, appreciate what animals do for us all, and understand how relatively wealthy I have become. Our ancestors in the hills had to be resourceful and clever to survive. I am honored to call them my kin.
