Cerulean Skies has convinced herself that life itself has been forever ruined by her very existence. She is miserable in school and life at home is no better. Crushing poverty has left her a bit cynical, a bit jaded, and some might say that her outlook on life has been soured. She is almost absolutely certain that her very existence has made the lives of everypony around her even worse. Her parents, her brother, all pegasus ponies who have to live on the ground to accommodate her. She came along and everything was ruined.
She might be right.
It doesn't make her questioning of everything any less relevant.
If it wasn't for her idol, Moondancer, she might go insane.
