Which themes of Henrik Ibsen's A Doll's House are reflected in this excerpt from act 1 of the play?
NORA (Smiling and humming): That's my affair! (Walking about the room) It's perfectly glorious to think that we have—that Torvald has so much power over so many people. (Takes the packet from her pocket) Doctor Rank, what do you say to a macaroon?
RANK: What, macaroons? I thought they were forbidden here.
NORA: Yes, but these are some Christine gave me.
MRS. LINDE: What! I?—
NORA: Oh, well, don't be alarmed! You couldn't know that Torvald had forbidden them. I must tell you that he is afraid they will spoil my teeth. But, bah!—once in a way—That's so, isn't it, Doctor Rank? By your leave! (Puts a macaroon into his mouth) You must have one too, Christine. And I shall have one, just a little one—or at most two. (Walking about) I am tremendously happy. There is just one thing in the world now that I should dearly love to do.
