why did persepolis do when she felt shame?

Marjane reads constantly of the reasons for the revolution. Her favorite author is a Kurd named Ali Ashraf Darvishian, “a kind of local Charles Dickens.” Darvishian writes stories of children that have been forced into hard labor. Because of these stories, Marjane finally understands why she feels ashamed when riding in her father’s Cadillac. “The reason for my shame and for the revolution is the same: the difference between social classes.” Then she remembers that they have a maid at home, which also makes her ashamed.
