Well...I already don't talk like a Vermontah...my parents are both from the Midwest and being a homeschooler, I really didn't pick up an accent or even most of the words people around here use.
Being in the military...well, I don't think I really changed my way of speaking any. Just picked up a love of some southern food. (There we go, back to food again...my hobbity tendencies coming out, I guess!)
At Thanksgiving, being overseas, generally one of the people in the shop would host the meal and provide the turkey (living in the dorms, I got out of this...all I had to do was bring soda / pop and some other easy stuff). There used to be some pretty heated discussions about stuffing - some people think if it ain't cornmeal, it ain't stuffing! It was always interesting seeing what were the traditional components of a Thanksgiving dinner in the various parts of the country.
Stuffing? We always go the oyster dressing route.
Thankfully we don't have that problem in our house. I stuff the turkey with apples, onions and celery, and serve mass quantities of cornbread dressing on the side!
