It is good of you to write, and I thank you for it: I am glad at last to hear from another of my kind—and, above all, to have another of my kind acknowledge me. I have indeed, since my return, heard many voices, seen many faces, but the individuals to whom they belong neither hear nor see me in return. I shake them, shout in their ears, but they do not respond. It is as if, for them, I do not exist. But why then, I wonder, would I exist for you? What is different about you? To put it bluntly, what is wrong with you?
