The protagonist’s main concept of family is her connection to her sister over many years. Though physically separated from all of her family members, Celie maintains her love and affection for her sister and two children for over thirty years. During her separation from her biological family, the protagonist becomes close to friends. Family members ultimately are the people that stick with you through thick and thin.
Because they are separated from their blood relations, both Celie and Nettie create families from scratch with the imperfect people that come into their lives.
