[Helmer:] Almost everyone who has gone to the bad early in life has had a deceitful mother.

Nora: Why do you only say—mother?

Helmer: It seems most commonly to be the mother's influence, though naturally a bad father's would have the same result. Every lawyer is familiar with the fact. This Krogstad, now, has been persistently poisoning his own children with lies and dissimulation; that is why I say he has lost all moral character. [Holds out his hands to her.] That is why my sweet little Nora must promise me not to plead his cause. . . . I assure you it would be quite impossible for me to work with him; I literally feel physically ill when I am in the company of such people.

–A Doll’s House,
Henrik Ibsen
