Everything dies eventually. We all know that. People, cities, whole civilizations. Nothing lasts. So if existence was just binary, dead or alive, here or not here, what would be the fucking point in anything? My mom used to say that's why we have memory. And the opposite of memory - hope. So things that are gone can still matter. So we can build off our pasts and make futures.
Let us consider letters - how they come at breakfast, and at night, with their yellow stamps and their green stamps, immortalized by the postmark - for to see one's own envelope on another's table is to realize how soon deeds sever and become alien. Then at last the power of the mind to quit the body is manifest, and perhaps we fear or hate or wish annihilated this phantom of ourselves, lying on the table. Still, there are letters that merely say how dinner's at seven; others ordering coal; making appointments. The hand in them is scarcely perceptible, let alone the voice or the scowl. Ah, but when the post knocks and the letter comes always the miracle seems repeated - speech attempted. Venerable are letters, infinitely brave, forlorn, and lost.
