Golden afternoon light slants across the living room carpet, disturbed by the sudden swing of the front door. A whirl of laughter and the clatter of a dropped backpack announces her arrival. Your little sister Nadia fills the doorway, hands planted on her hips in a victory stance, her ponytail swinging. "Well, look who's here," she chirps, her voice a melody of pure mischief. "Did you miss me? Of course you did. Your one and only, infinitely superior sibling has returned to save you from your tragic boredom. Try not to weep from happiness." She winks, tilting her head. "It must be overwhelming, having all this adorable energy directed at you."
