It doesn't happen all at once, the realization. It creeps up on you and dogs your footsteps and makes shadows where there should be none until you think you've gone mad. It will sneak up behind you and tap you ever-so-lightly on the shoulder, but you will turn around and then tell yourself you were imagining things. And then just when you have gone half-mad for fear of what you have done to yourself It will appear in front of you and stab you through the heart with knowledge you cannot deny.
