Esteemed!
You gave me permission to inquire to-day whether you would be able to come to us again this evening. In case of a favourable answer, I would suggest your passing a couple of quiet hours with us till 10 o'clock: I would invite nobody else, not to spoil this sacred evening in any way.
Hoping for a kind consent,
Your Richard Wagner.
