I will never forget when our farm help went to college at SIU and came back with a goddamn southern accent. We lived closed enough to Wisconsin to spit on it.
It happens. I would spend summers as a teen in Swansboro, NC and I loved to hear those sweet North Carolina girl's accent. It is the only Southern accent I like. Once back in Iowa, my family gave me a few months to get my speech back to normal. It's the heat I think that gets you.
