I LOVE regionalisms, eh. I don't mind all the little things people say, but I do cringe when the verb doesn't agree with the subject, especially when the person is answering the phone. And I know some people are trying really hard to get it correct, and goof it up everytime! Double negatives confuse me, but I can usually figure out what the person means. Sometimes not. Or "not so much" which is the new one.
I like listening to people and I try to determine where they have lived because they use words in unusual ways.
