Read the excerpt from act 3 of A Doll's House. Mrs. Linde: We have a great deal to talk about. Krogstad: I shouldn't have thought so. Mrs. Linde: No, you have never properly understood me. Krogstad: Was there anything else to understand except what was obvious to all the world—a heartless woman jilts a man when a more lucrative chance turns up? Mrs. Linde: Do you believe I am as absolutely heartless as all that? And do you believe that I did it with a light heart? Krogstad: Didn't you? Mrs. Linde: Nils, did you really think that? Krogstad: If it were as you say, why did you write to me as you did at the time? Mrs. Linde: I could do nothing else. As I had to break with you, it was my duty also to put an end to all that you felt for me. Krogstad [wringing his hands]. So that was it. And all this—only for the sake of money! Mrs. Linde: You must not forget that I had a helpless mother and two little brothers. We couldn't wait for you, Nils; your prospects seemed hopeless then. Krogstad: That may be so, but you had no right to throw me over for anyone else's sake. Mrs. Linde: Indeed, I don't know. Many a time did I ask myself if I had the right to do it.
