Act III was so sad!!!

 Throught that the end of A Doll's House was really sad. But I feel think Nora finally stood up to Torvald and showed him who she really was. When Torvald was begging Nora to stay it was sad but he deserved as well. He treated Nora like a child and always thought that Nora couldn't do anything her own but she showed him. I think Nora left Tovald for two reasons, one she was tired of being Tovald's 'doll' and two, she wanted to start over with her life. I wonder what would happen if the play continued where it ended?
