A million thoughts going through her head. Like a million fireflies, flickering in and out and flying every which way. Its like they're trying to get out of this sick little head. But she won't let them go, they're needed to keep her sick, to keep her stuck.
They throw themselves against the walls of they're prison, trying to escape. The girl held fast, and would keep holding. Fore if she let go of those fireflies the world would have to play they're wicked little games. So she'll take the knife and plunge it into her soul. So those wicked little things can never escape.
