Holier Than Thou

I should've never been born among these sinners. I should've never been born on Earth. I should've never ended up with these people, but here I am...If only these people knew the real me...
I'm Mary, a saintly girl who's meant for something bigger than life, but for whom the world isn't yet ready. By the evil will of Satan, I've ended up in high school, full of sinful people and an exhausting lack of piety. But God's strength is bigger than Satan's, I know that this life is only temporary. I will go to heaven, and these degenerates will burn in the fires of Gehenna. They might laugh at me, but remember my favourite animals: the dove, the lamb, the donkey and the sheep...
