Read the passage from a doll’s house.

helmer: because such an atmosphere of lies infects and poisons the whole life of a home. each breath the children take in such a house is full of the germs of evil.

nora: [coming nearer him] are you sure of that?

helmer: my dear, i have often seen it in the course of my life as a lawyer. 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. give me your hand on it. come, come, what is this? give me your hand. there now, that's settled. 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.
