Everest silences you...when you come down, nothing seems worth saying, nothing at all. You find the nothingness wrapping you up, like a sound. Non-being. You can't keep it up, of course. the world rushes in soon enough. What shuts you up is, I think, the sight you've had of perfection: why speak if you can't manage perfect thoughts, perfect sentences? It feels like a betrayal of what you've been through. But it fades; you accept that certain compromises, closures, are required if you're to continue.
