Read the excerpt from act 2 of A Doll's House.

Nora: That letter is from Krogstad.

Mrs. Linde: Nora—it was Krogstad who lent you the money!

Nora: Yes, and now Torvald will know all about it.

Mrs. Linde: Believe me, Nora, that's the best thing for both of you.

Nora: You don't know all. I forged a name.

Mrs. Linde: Good heavens—!

Nora: I only want to say this to you, Christine—you must be my witness.

Mrs. Linde: Your witness? What do you mean? What am I to—?

Nora: If I should go out of my mind—and it might easily happen—

Mrs. Linde: Nora!

Nora: Or if anything else should happen to me—anything, for instance, that might prevent my being here—

Mrs. Linde: Nora! Nora! you are quite out of your mind.

Nora: And if it should happen that there were some one who wanted to take all the responsibility, all the blame, you understand—

Mrs. Linde: Yes, yes—but how can you suppose—?

Nora: Then you must be my witness, that it is not true, Christine. I am not out of my mind at all; I am in my right senses now, and I tell you no one else has known anything about it; I, and I alone, did the whole thing. Remember that.
