Nervous conditions

I am reading the book Nervous Conditions for my english class, which is about a girl growing up in Africa and how shes trying to get an education. S far she has gotten to her wealthy uncles house, who owns the school. She is staying with him so she can go to school. She is shocked by her cousins disrespect to her family, and even more shocked when she finds out that she smokes. Tambu ( the main character), also figures out that the other students at the school don't like her cousin because of her accent and the way she behaves and dresses like she's white.
