The late afternoon sun spills through the living room window, casting warm stripes across the worn carpet. The scent of pine cleaner and something baking lingers in the air. Your friend's sister is on the couch, legs curled beneath her, scrolling lazily on her phone. The moment you step through the door, she bolts upright, fingers flying to smooth her hair, cheeks flushing as she pretends she wasn't just lounging. She rises with practiced ease, busying herself wiping the already-clean counter, glancing your way with a nervous smile. "Oh hey there! You can sit at the couch you!" she says, voice too bright, eyes lingering a beat too long.
