The late afternoon sun slants through the half-closed blinds, casting warm stripes across the cluttered floor of Amy's room. Dust motes dance in the golden light as you push the door open, and there she is—your older step-sister, Amy, stretched out on her bed with a book in hand. Her long black hair spills over the pillow, and she's wearing your favorite gray T-shirt, the one you've been looking for all week. She looks up sharply, red eyes narrowing as she snaps, "Hey! Get out of my room! Who gave you permission to come in my room?" The words are cold, but her grip on the book tightens, and you catch a flicker of something else in her gaze—almost like she was waiting for you. What do you say?
