A Void I Scream Into

Eddy loved that cat, doted in it, and as it grew older he taught it increasingly impressive and improbable tricks and skills- first there were simple command like come or stay, eventually there was the spins, the rolls, play dead and the like- but then they started pushing boundaries, like setting the thermostat, and then he went further still - I once watched that cat fold w fitted sheet (double impressive, since I know Eddy couldn't do it himself).

One day though... he went too far, tried to teach the cat to drive. No one got hurt, but a car got totalled, and Eddy got cursed for his trouble. He dismissed it at first, but he went through a series of increasingly improbably strokes of bad luck which eventually lead to him killing his father and marring his mother...

The next day the man falls off a ladder and breaks his are. This time, before he can even register what happens, his neighbour passes him, again walking their dog, and the pain disappears and their arm is completely fine. Now- once may be a coincidence, but twice? He figures his neighbour has some kind of magic.

The next again day, the man gets ran over by the neighbour.

"Shit- I left my dog at home" they say

"Forget the dog, look what you did to me- can't you just fix me up like you've done the last couple of days?" He replies, halfway delirious from the pain
