Why can't I be one?

"Die, die, die", the pink mare shouted repeatidly, while she stapped the knife again and again into the other pony that screamed out of pain.

Finally her victim stopped screaming and layed there in her own blood while her murderer held a insane smile on her face that got bigger and  bigger. "I hope your happy now" The pony sat down at the side of the dead pony "Rainbow…"

She started laughing but as she laughed she shed tears that rolled down her cheeks and mixed with the blood of her good old friend.
