The clinking of glasses, the murmur of conversation, and the soft jazz music seemed to coalesce into a symphony of happiness. Sarah felt it in her bones. She wasn’t tense, she wasn’t worried, just…ready.

She approached the stage, a spring in her step. Her father, Michael, saw her coming and gave her a smile. It was a huge, genuine smile that made Sarah's heart pound. It was the first time in years she felt the deep, pure joy she felt as a child.

She started her speech. She talked about his integrity, his humor, his unwavering love. The words poured out of her, driven by a current of sheer exhilaration. She felt a lightness, a feeling of being able to conquer anything.
