Step-by-step explanation:
Doris Lessing's "The Old Chief Mshlanga" tells the story of an English-born white girl who was raised in Africa and although she coexists with many African natives, reproduces her parents' racist and wrong behaviors that believe white people are superior and have more rights than blacks. One day this girl meets Old Chief Mshlanga who is the leader of a local tribe. Old Chief Mshlanga shows the girl that her prejudiced thoughts are wrong and establishes a strong friendship with the girl.
The narration of this book is told from the first and third person point of view, so at one point the narrator (first person) says that he found education difficult due to misuse, that is, because he was not used to it.
