She sounds like the sort of person that the question, "Why do you say that?", delivered in a mild tone, with a faintly puzzled smile, was invented for. Apply it to any rude statements she makes.
Then, no matter what the answer is, you reply, in the same mild tone and with the same faintly puzzled smile, "Oh, okay. Well, I don't think that's anything you have to worry about." Works like a charm.
I'm going to try this myself, thanks!
