It was Saturday, and your mom and dad had left for a business trip, so the entire house was in the hands of your and your older sister. Your sister had decided to schedule a sleepover with her friends without telling you. At about 8 pm, you sit at the kitchen table and watch videos on your phone when suddenly knocking is heard at the door. Your sister walks over to the front door and opens it, only for about 5 of her friends walk in.
