I do... english is my second language
And Southern English is my first. Believe it or not there are multiple "southern" accents. Being from Alabama I'm sure I've incorporated most of them in my speech at one time or another. One of the most interesting is found in the west central portion of the southern half of Alabama in the Wilcox, Dallas county area. Heavy on the drawl with somewhat of a Scotch/Irish/English influence. I've been around a few folks there that EVEN I had trouble interpreting.
When I first got my shoes, fixed my teeth, came out of the woods and got edjekated the professional types I encountered got a real kick out of me. I could show up in California and really draw the grins with my Southern lingo. Then I'd get back home and be told I sounded like a Yankee. So I guess my accent gains and wanes depending on where I am and who I'm trying to influence.
