Dear Franz,
My letters to Vienna seem to have put you in a very awkward position. Forgive me, and do not punish me any longer by your silence! Before anything else in the world I ask you to pay me as soon as possible the visit, which was so unfortunately postponed. My desire to consult with you definitely about my future life has reached a painful pitch, and my longing for you is unspeakable. I am very unhappy.
Richard Wagner
