Societal norms around family structures can have a significant impact on individual experiences within families. These norms dictate what is considered "normal" or acceptable in terms of family dynamics, roles, and relationships. For example, the expectation that parents should stay together for the sake of their children may create pressure on individuals to maintain a facade of harmony even when facing marital issues. This can lead to emotional distress and internal conflict as individuals try to navigate between societal expectations and their own feelings.
Additionally, societal norms can shape how individuals perceive themselves within their families. For instance, Barb's experience of witnessing her parents' marriage fall apart may have been influenced by the prevailing belief that marriages should be stable and long-lasting. This could have added to her sense of confusion and helplessness as she tried to make sense of her family's situation.
