Jane Austen - Northanger Abbey
“What are you thinking of so earnestly?" said he, as they walked back to the ballroom; "not of your partner, I hope, for, by that shake of the head, your meditations are not satisfactory."
Catherine coloured, and said, "I was not thinking of anything."

Jane Austen, Northanger Abbey
