It’s the leftover humans.
The survivors.
They’re the ones I can’t stand to look at, although on many occasions I still fail. I deliberately seek out the colors to keep my mind off them, but now and then, I witness the ones who are left behind, crumbling among the jigsaw puzzle of realization, despair, and surprise. They have punctured hearts. They have beaten lungs.

--Yet another brilliant quote from The Book Thief
