what was nhamo's attitude to his sister

He liked to have power over his female relatives. While Nhamo is going to school, he makes his female relatives carry his luggage when he returns home. Tambu knows that "he did not need help, that he only wanted to demonstrate to us and himself that he had the power, the authority to make us do things for him." From the first chapter of the book, Tambu states that "the needs and sensibilities of the women in my family were not considered a priority, or even legitimate."
