All these months I’ve tried to imagine this situation. Who am I, here, and who are they? What voice will I have? Will I understand their voices? I interrogated several of the teaching assistants who had already offered classes at the prison. One warned me that my being a woman is a distinct disadvantage. They will associate me, he thinks, with naggy high-school teachers. From this conversation, I take away a new anxiety: I will remind them of an earlier stage of unfreedom.
