When Paul D confronts Sethe with the newspaper clipping, she begins to circle frantically around the room in a manner that parallels the circular manner in which she unravels her story for him. She tells Paul D how, at 124, she began to love her children with renewed force, because she knew finally that they were fully hers to love. When she recognized schoolteacher’s hat outside the house one day, she felt hummingbird wings beating around her head and could think only, “No. No. Nono. Nonono.” Killing her children was a way of protecting them from the horrors of slavery she had herself endured, a way to secure their safety.
