"How could they learn, if no one gives them a chance?"

If everyone wrote off every problem child, every person who was even remotely "a burden". No one would ever get the chance to learn. They'd never get the chance to be better. To live up to their potential. If Sam Holt hadn't given Shiro a chance, he never would have been there to give one to Keith.

"Some people get written off too soon. They make a mistake, the world gives up on them. And... they just need a hand up."
