Why do the Mannings sound like they have a Different accent ??

OK here's my take on accents growing up in Louisiana. I was born and lived in Lafayette until I was thirteen. My two best friends and I were wasps and I never realized any accents on any of us before I left. My family moved away and I lost contact with my two friends, then college and moving around the country. About ten years ago I was in Lafayette overnight and I decided to try to contact my two childhood friends. Lo and behold I talked to them on the phone, but they had developed a pretty acute cajun accent. I couldn't believe it. I even mentioned to them that if my family hadn't moved I may have developed one also. Now I'm out in Southern California and not too long ago I was talking to someone and they asked "Are you from Southern Georgia?" I guess whatever environment you are in develops how you speak.
