A Doll's House
How we cite our quotes:
NORA: "How painful and humiliating it would be for Torvald […] to know that he owed me anything! It would upset our mutual relations altogether." (1.197)
The Helmers' marriage is based on maintaining a veneer of male dominance.
NORA: "Christine is […] is frightfully anxious to work under some clever man, so as to perfect herself--" (1.282)
Nora's relationship with her husband seems to be built on careful manipulation of his ego.
NORA: "But don't you think it is nice of me, too, to do as you wish?"
HELMER: "Nice?--because you do as your husband wishes? Well, well, you little rogue, I am sure you did not mean it in that way." (2.82-2.83)
Comments like this from Torvald demonstrate that the Helmers are in a lopsided marriage.
