As long as I stared at the clock, at least the world remained in motion. Not a very consequential world, but in motion nonetheless. And as long as I knew the world was still in motion, I knew I existed. Not a very consequential existence, but an existence nonetheless. It struck me as wanting that someone should confirm his own existence only by the hands of an electric wall clock. There had to be a more cognitive means of confirmation. But try as I might, nothing less facile came to mind.
