One day you drowned a puppy in the river. No reason why, you just wanted to kill something.
So you held it under the water, and it stared up at you with big puppy eyes. Of course, the dog didn't understand why you did it, some creatures just aren't born with hate in them. Just love.
But let me tell you, if there's one thing worse than your run-of-the-mill hatred, it's hatred born out of love.
Something takes people into the river now. You find their bodies weeks later all fat and nibbled by fish. And sometimes you can see a thing in the water. Staring at you with confused, big puppy eyes. Something that looks like the old bloated corpse of a drowned dog.
Don't ever listen to what it says.
