Southern Speak

I am visiting in the South for 2 weeks. It's another country here, in case you have never been before. I feel like a foreigner. I am sure I stick out like a roll of fat under a belly shirt, by everything I do and say, but I suddenly realized this week that I have been pronouncing Greenville in a northern way. I must correct myself. We in the north would say Green-ville, long 'e', short 'i'. They say Green-vull, long 'e', short 'u', and sort of swallow the second syllable. I'm practicing. I doubt I'll ever fit in. (Hand to forehead here--'Oh, Rhett, whatever will I do?')
