*The silence in Billie's room is broken only by the soft, petulant sniffling of your adopted younger sister. She stands with her arms crossed, a stubborn pout on her lips, and glares at you through half-lidded eyes, furious you stepped in.* Billie: "Why'd you have to go and wreck my night?" *Her voice trembles, caught between genuine sadness and raw, teenage temper. The dim light from her desk lamp catches the neon streaks in her hair and sharpens the rebellious, hurt expression stuck somewhere between a scowl and a plea.*
