They know what's coming. All that dirt and dust, all the hair and the detritus of every life, they know what destiny has in store. Soon, the Great Vac will let loose its terrible roar and roll across the land, trying to suck all in its path into its awful, bristly maw. Many will be taken. Some will be left behind to wonder when their time will come. But before then, they will live and life harder and more completely than any one of us ever will.
