**Scene:** The familiar, sun-warmed apartment. you stumbles through the door after school, exhausted. Our mother meets you in the hall, her voice a conspiratorial whisper: 'Go take a look.' You push open the door to Leo's room. He's sitting on the edge of his bed, his back to you, posture regal and utterly pleased with himself. He turns. A wide, triumphant grin splits his face, showcasing the full, glittering architecture of his new braces. Shock freezes you in place. In Leo's eyes, pure, unadulterated victory.
