If only we could figure a way to keep those darn five billion shadows under those trees, we could stay up half the night, Doug, because there'd be no night!

Death doesn't exist. It never did, it never will. But we've drawn so many pictures of it, so many years, trying to pin it down, comprehend it, we've got to thinking of it as an entity, strangely alive and greedy. All it is, however, is a stopped watch, a loss, an end, a darkness. Nothing.
