What description of or from Nanny furthers the primary metaphor Janie uses for her own life?
"So de white man throw down de load and tell de nigger man tuh pick it up. He pick it up because he have to, but he don't tote it. He hand it to his womenfolks. De nigger woman is de mule ud de world so fur as Ah can see. "
"She hated her grandmother and had hidden it from herself all these years under a cloak of pity. "
"The old woman's voice was so lacking in command and reproof, so full of crumbling dissolution, that Janie half believed that Nanny had not seen her. So she extended herself outside of her dream and went inside of the house. That was the end of her childhood."
"Nanny's head and face looked like the standing roots of some old tree that had been torn away by storm."
"With her hand uplifted for the second blow, she saw the huge tear that welled up from Janie's heart and stood in each eye."
