“ Remember: You are no one. You have no name. You do not speak, you do not look at them, you do not volunteer for anything. You work, bot not so hard they notice you. Gizela. Zytka. Your parents, Oskar and Mina. They are dead and gone now, Yanek, and we would grieve for them if we could. But we have only one purpose now: survive. Survive at all costs, Yanek. We cannot let these monsters tear us from the pages of the world. ”
