I frequently greet patron's with a cheery "Hi!" followed by one of two questions:
"What can I help you with?"
"How are you today?" (this second one is especially appropriate when they have a stack of books ready to check out...I know how I can help them, I don't need to ask!)
Today, I asked a patron how she was, and got this answer:
"I'm finer than a frog's hair split three ways and sifted through silk."
I'm not going to lie, I didn't really know what to make of that response. She said it very very cheerfully, and obviously any such hair would have to be very, very, VERY fine, thus making her very happy. Except...frog's don't even have hair, do they? And if that's the case, then maybe she was trying to say that she was really unhappy?
I honestly don't know.
