Death was never quite sure why he allowed the Death of Rats to have an independent existence. After all, being Death meant being the Death of everything, including rodents of all descriptions. But perhaps everyone needs a tiny part of themselves that can, metaphorically, be allowed to run naked in the rain, to think the unthinkable thoughts, to hide in corners and spy on the world, to do the forbidden but enjoyable deeds.
― Terry Pratchett, Thief of Time
