It's been ten years already.
I can't say that it's been easy; being stuck in here while somepony else leads my life has been one of the hardest things not to cry over. But I'm here, after a decade, and I haven't shed a tear. Emotionally hardening yourself isn't so hard after almost losing your sanity. Besides, I've had dozens of months to face the issue at hoof. I understand, accept and believe the fact that I am being tortured... but I also know that I will break free.
That wretched excuse of a pony has kept me locked up in this dark, dark place for too long. But soon, all the suffering will be over. Because after all these years, I can initiate the plan I've been working on for ages. And this time, I will not fail.
I will free myself from this prison, and I will change the world. She will soon learn that life is not just sunshine and rainbows. Because both, as anything else, can always be viewed...
In shades of grey.
