Often people don't even realize they can question their family relationships or the role they played within the familial structure. Bradshaw explains how, as a social system, all families need the structure that roles provide. In functional families, roles are flexible; they shift in understandable and somewhat predictable ways according to circumstances, external demands, and family members' needs. In dysfunctional families, roles tend to be rigid and unpredictable. Still, they often go unchallenged or unexamined.
