Letters, symbols and signs are my closest allies because they never change. They just stay as they are, fixed in my memory. And whenever we’re lonely or happy, in the same way that you might half hum a song to yourself, we summon up our letters. When I’m writing them out, I can forget everything else. I’m not alone when I’m with letters. Letters and symbols are much easier for us to grasp than spoken words, and we can be with them whenever we want.
