Explanation:

In the play A Doll's House, Nora's behavior of being overly friendly (smiling, engaging in conversation) while having an ulterior motive (manipulating for a favor) is a key dramatic element. The audience can observe her actions and infer her true intentions, while Doctor Rank, caught up in the moment and his feelings, does not realize he is being manipulated.
