'The more I read the book, the more wonderful it seems to me. It is really a great book. Arthur says, and I more than agree with him, that the passage about Pyramus and Thisbe will, in the future, be regarded as one of the greatest passages in English literature. As I say, I agree, but the whole book in its entirety is to me like some wonderful and unspeakably moving music. It excites one, moves one, intoxicates one to an incredible degree. The worst is, it unfits one for daily life. To have to eat one's lunch in the middle of reading it is practically impossible. And I got, literally, no sleep after it, on Friday night. I couldn't sleep after it. This isn't talent - not even great talent- not even a great gift - it is genius. You know what my pride in you is. I am most terribly proud to be your sister.'
