Writing is the process of trying to create a world in words. You write it into being, a literary Genesis, and people it, and breathe life into it, and the life is in the words. The right words make it real. If you get the words right, there is a world of emotion and conflict and joy and struggle, with rain drops on the windowsills and breath forming visible puffs of mist in the cool air. If you get the words wrong, you have a cardboard construct and the things that would make it real are missing. Nobody breathes, no rain falls. If the devil is in the details, the world is in the words.
