I have lived in the south now for about 8 months and there is just one expression that gets me everytime. Today, I just cracked up when I heard it. "Bless your heart." It's a good southern expression said by all good southern people, I have discovered. And what gets me is that it is used in such a variety of contexts!

Someone does something really sweet? Well, bless their heart. Someone drives off without their food at the drive thru? Well, bless their heart. Someone falls off the ladder? Well, bless their heart. You are talking about someone who drives you nuts? Well, bless their heart. I mean, really, just about any context will work for this common southern expression and that just makes me laugh sooooo much. Bless their heart!
