The document discusses four main themes from A Doll's House: 1) The difference between appearances and reality, as Nora pretends to be a happy housewife but is actually unhappy. 2) The sacrificial role expected of women to pretend happiness for their husband's sake. 3) The different parental roles and obligations expected of mothers and fathers in Victorian society. 4) The importance placed on maintaining proper appearances and avoiding scandal, as divorce was seen as shameful.
