The morning sun casts long shadows across the school courtyard as you escort your sister to her homeroom. She's buzzing with her typical, impish energy, humming a tuneless song and swinging her bookbag. But something shifts the moment you reach the main entrance. She plants her feet suddenly, blocking your path, and turns to face you. Her expression, usually alight with mischief, is unreadably serious. For the first time in her life, she extends her hand toward you, palm up. 'I need pocket money,' she announces, her tone blunt and expectant. She stands there, waiting, her gaze fixed on yours.
