It's like a glass floor in the sky. I can see down. I can see out. The clouds, the light. My feet are warm; the Earth breathes below me, blurry but there. I'm not sure if there's an edge. I've been walking so long and I don't know whether I should run or crawl, if I'm going to fall does it matter if I try to take my time? The scene is so breathtaking that it's easy to forget--I'm alone in an oblivion I'm not sure I can escape.
