Whom are you going to dance with?' asked Mr. Knightley. She hesitated a moment and then replied, 'With you, if you will ask me.' Will you?' said he, offering his hand. Indeed I will. You have shown that you can dance, and you know we are not really so much brother and sister as to make it at all improper.' Brother and sister! no, indeed.
