Read the following scenario. Analyze the specific dysfunctional communication patterns present within the family's interaction. Explain how these patterns contribute to conflict and why they would serve as a primary rationale for the family to seek therapy together.

Scenario: The Miller family consists of two parents and their 15-year-old son, Leo. During a disagreement about Leo's curfew, his mother says, 'You never respect our rules; you're just trying to be difficult.' Leo retorts, 'You always assume the worst and don't even listen to my side.' His father then interrupts, stating, 'That's enough. This conversation is over. You're grounded.' Leo storms off to his room, feeling unheard, while his parents feel disrespected, believing Leo's behavior is the sole problem.
