The therapist guided them through small experiments: one week devoted to gratitude notes left on the refrigerator, another to allotted “safe” conversations where each person had uninterrupted time to speak. At first the notes were awkward—“Thanks for making coffee”—but slowly they grew more sincere: “Thanks for driving Mara to practice when you didn’t feel like it,” “Thanks for listening when I was scared.” Those small affirmations, ordinary on their face, began to erode the hard shell they’d built.
