The title A Doll's House has been cleverly used by Henrik Ibsen to set the scene of this play even before it begins. The audience expects that reality will be questioned in a play that effectively creates a life-size doll's house where real-life activities will take place.
It is fitting that the game that Nora plays with her children is Hide-and-seek. Nora is hiding behind a facade because it is expected of her. She knows the role she is supposed to play is not the role she is actually playing. Women should not concern themselves with - indeed they are unable to comprehend anyway - money and business affairs.
Nora's indiscretions are heartfelt and very real and her intentions - to save her husband - are pure. However, this just reinforces the position Nora holds as she"hides" from reality. This concept is prevalent throughout the play.
