After Joe’s funeral she observes in her unhappiness how Nanny had taken "the biggest thing God ever made, the horizon" and "pinched it in to such a little bit of a thing that she could tie it about her granddaughter’s neck tight enough to choke her." At the end of the novel, though, Janie is able to "[pull] in her horizon like a great fish-net" with a delighted, peaceful heart. Explain why Nanny’s horizon was so restrictive for Janie and what led to its great expanse at the end. Use at least two examples of textual evidence to support your answer. Your answer should be at least two hundred words.
