This is the way the world ends: not with a bang, but with a whimper.
At the end of everything, not jst one planet or species or life, but of all existence, there will be three entities observing. One will watch with some amount of sorrow, for he was responsible for all of it in the first place. The other will watch with some amount of pity, for he found a great deal that he recognized in all of it. The third will watch with a kind of regret, for he will no longer have anyone to accompany him while he sings.
