고맙습니다 vs. 감사 합니다 Almost always, when I hear my wife thank someone for something, she says "거맙습니다," or "고마워요." Most of her acquaintances use this expression when talking to her, and when we're in Korea, I notice her brothers and sisters almost always use a variation of this. Because of this, it became very natural for me to thank someone like this, too, but there are sometimes when I get gently corrected (actually just get a suggestion) to use 감사 합니다. I notice that in the business emails, people always use 감사 합니다, and that's what I hear in business context. (I should say that my wife and her family are from 부산, and it's very easy to tell when they speak :). I don't think this is the only difference, though, because I know I've heard other accents use "가맙습니다," too). Can someone please explain tendencies to use one vs. the other, and are there places where it is appropriate to use one term, but not the other? or is it just tendencies?
