Shortly after moving to Texas, my wife and I went into a grocery store to buy Mountain Dew. I spotted a lady stocking a freezer and decided to ask for help. As I approached I said, "Excuse me, ma'am. Where do you keep the pop?" She slowly turned to me. In a loud shrill voice she proclaimed, "Ya'll aren't from around here, are ya? Ya'll sound like a bunch of damn'd yankees! The cokes is over there." :o
According to one person in Houston I speak "Yankee".
I'm as multilingual as Homer Simpson... "Le Grille! What the hell is that?" ...with one exception: I can understand a bit of Texan.
As far as progamming languages, the list is embarassingly long. I'll just say C++ and ObjectPascal (aka Delphi). I learned C in college and ObjectPascal for work.
