The document discusses how stage directions in Henrik Ibsen's play "A Doll's House" effectively portray changes in the personality of the protagonist Nora and her relationships with other characters. Specifically, stage directions show Nora's defenselessness and fear when first blackmailed, her inability to pretend nothing is wrong after learning a secret, and her realization of her husband Torvald's true character and decision to leave him and her children at the end of the play. The stage directions enhance the dramatic tension and help readers visualize the characters' actions and evolving emotions throughout the major revelations and changes that occur over the course of the play.
