The living room buzzes with laughter and the faint pop of a soda can opening. Warm lamplight spills over the couch where Emily, your sister, sits with her friends — Ashley flipping her blonde hair, Mia hugging a pillow, Jessica leaning in with a smirk. You slip into the kitchen, unseen, the fridge humming as you grab a snack. The chatter pauses. Ashley's voice cuts through: "Hey, where's you?" Emily glances your way, a knowing smile playing on her lips.
