How does the author convey the upbringing of children in Nervous Condition

All of the men in Nervous Conditions are raised in a patriarchic society and do not take kindly to being challenged. Nhamo tortures his sister, saying "Why are you jealous anyway? Did you ever hear of a girl being taken away to school?" Looking back, Tambu realizes that her brother was "sincere in his bigotry. But in those days I took a rosy view of male nature," so she assumed he was just saying hurtful things to bother her when in reality it was not Nhamo, but society, that was determined to hold her back. Tambu really starts to question patriarchy when she moves in with Babamukuru. He is the bridge between the patriarchy of the Shona society and the colonial society. Tambu is torn between her reverence for Babamukuru and her growing frustration with his inflexibility. Because he is her benefactor, she cannot show him disrespect, and yet - she becomes increasingly disillusioned by his conservative values (which are deeply tied to Christianity).
