In A Doll's House, how does the presence of Mrs. Linde display Nora's character?
In A Doll's House, Nora is content to be considered as her husband's "little squirrel." She allows his control of her but also enjoys defying him by eating macaroons, a seemingly fickle act which masks a much deeper secret. This reveals her contradictory nature which is reinforced by the arrival of Mrs Linden, Nora's old school friend, whom Nora does not instantly recognize. The fact that Nora chatters and rambles at first does show Nora to be shallow. She is tactless and inconsiderate, "Poor Christina ! I forgot :you are a widow." Nora is more concerned about the fact that Christina was left with "Nothing" and the almost shame of such a thing and that she has no children, than she is for her friend's well-being, clearly indicating Nora's stereotyped views.
Nora's insincerity becomes obvious as "To-day I'll think only of you" but without giving Christina a chance to speak, she immediately informs her of Torvald's promotion and their "good fortune." Her priorities seem questionable. Nora is also keen to make Christina understand her own sacrifice. Her need to be liked is evident, constantly seeking Christina's approval. When the conversation does return to Christina, it is because Nora wants to know why she married a man she did not love. When Nora remarks, "How free your life must feel" this also reveals how trapped in her own existence she is.
Nora's obsession with how she thinks life is supposed to be and with expectations and social norms foreshadows her realization at the end that her own character is lacking and she needs to do something about it. Her feelings of betrayal are intense.
