Dearest friend,
That I ran away from you was a perfect inspiration, which should bring noble fruit both to you and to me. I shall go to bed at nine; do you likewise, and sleep by the book, so that we may present to each other tomorrow morning a couple of fresh faces, ready to face the world. I shall study Mephistopheles a little today. If you like we will do some Valkyring tomorrow. May a thousand gods protect you.
Richard Wagner
