For "A Doll's House", provide evidence that Nora becomes an independent thinker.
Nora begins the play by being subservient. She hides the macaroons that she wants to eat because Torvald does not want her to have them. She expresses a desire to say "damn" in front of Torvald, but doesn't consider actually doing it. When Krogstad warns her of how serious her act of forgery was, Nora is hesitant to accept his seriousness. However, when Torvald goes on his rant about how criminal behavior can affect a home, Nora becomes so scared that she refuses to see the children.
However, in Act 5, Nora has come to think for herself. Torvald reacts to the news of the letter with anger, expressing how much this situation will hurt him. Nora is immediately turned off. She is angered more when Torvald so quickly 'forgives' her at Torvald's second letter, because this proves that he only cares about his own reputation. It is at this point that she no longer gives in to his emotions and his desires.NORA: [looks steadily at him and says with a growing look of coldness in her face]. Yes, now I am beginning to understand thoroughly.
She demands that they sit down and talk, and she insists that she has never really known him. She actually cuts Torvald off and demands he listen to her:NORA: You don't understand me, and I have never understood you either—before to-night. No, you mustn't interrupt me. You must simply listen to what I say.
And, of course, she does walk out at the end.
