" I've never thought of you like that,' said Christopher. 'How could I? If you were any other woman, I could tell you I loved you, easily enough, but not you-- because you've always seemed to me like a part of myself, and it would be like saying I loved my own eyes or my own mind. But have you ever thought of what it would be to have to live without your mind or your eyes, Kate? To be mad? Or blind? "
