My dear friend,
Go ahead! I am delighted to hear of your plans, and especially that you mean to address your communication to me. Is anything more than this assurance needed to encourage you to undertake your task with enthusiasm?
Our friends Nietzsche and Gersdorff were in Munich a few days ago to attend a performance of Tristan; in fact, I am expecting Gersdorff to stop over in Bayreuth on his way back to Berlin. As for me, I am engaged in finishing off my monstrous opus and am feeling quite well, as is also my dear wife, who joins me in sending you cordial greetings.
I hope that all goes well with you.
