On chapter three What are Kumalo's fears?

he worries about the fate of his sister, the cost of the trip, and the possible adversities he might face. He remembers the story of Mpanza, whose son Michael was killed in the street of Johannesburg when he inadvertently stepped into traffic. His most pressing fear, however, concerns his son. Before the train leaves, Kumalo's companion asks him to inquire about the daughter of Sibeko, who has gone to Johannesburg to work for the daughter of the white man uSmith. (the last name is, as expected, actually Smith; the prefix u- serves the same function as Mister in Zulu). Sibeko himself did not ask because he is not a member of their church, but Kumalo insists that he is of their people no matter. Kumalo travels with the fear of a man who lives "in a world not made for him, whose own world is slipping away."
