Read the passage from A Doll’s House. Nora: Hide the Christmas Tree carefully, Helen. Be sure the children do not see it until this evening, when it is dressed. [To the porter, taking out her purse.] How much? Porter: Sixpence. Nora: There is a shilling. No, keep the change. [The porter thanks her, and goes out. Nora shuts the door. She is laughing to herself, as she takes off her hat and coat. She takes a packet of macaroons from her pocket and eats one or two; then goes cautiously to her husband's door and listens.] Yes, he is in. [Still humming, she goes to the table on the right.] What do the stage directions tell the reader about Nora?
