Erik Satie never used to open the letters he received, but he always answered them. He would check the sender’s name and address and write a reply. After he died, his friends found all those unopened letters and some felt quite upset, but there was no need to be. The letters were published alongside Satie’s replies, and the results were fascinating. Ricardo Piglia wrote: “This is an amazing correspondence in which everyone is talking about different things, which is, of course, the essence of dialogue.”
