One regional phrase here (W.KY) that always causes confusion for people that are not from the area is "I don't care to". Most people that are not from around here take it as someone saying they are not going to do something. If you ask someone "While you are by the book on the table would you hand it to me?" The other person would probably say "I don't mind to at all." What they mean is yes and it doesn't bother them to do it. It is like they are saying it is no trouble for them and they are happy to do it for you. I have seen some people that are not local get VERY upset because they thought the person was telling them no. That is one of the most common misunderstanding I have noticed. Most of the times sayings and words just lead to confusion but this is one that really causes problems until it is understood what the locals mean.
