Grandmother pointed out my brother Perry, my sister Sarah, and my sister Eliza, who stood in the group. I had never seen my brother nor my sisters before; and, though I had sometimes heard of them, and felt a curious interest in them, I really did not understand what they were to me, or I to them. We were brothers and sisters, but what of that? Why should they be attached to me, or I to them? Brothers and sisters were by blood; but slavery had made us strangers. I heard the words brother and sisters, and knew they must mean something; but slavery had robbed these terms of their true meaning.
