My younger sister is such a b**** but no one sees it. She is rude to everyone in my family yet never gets into trouble. She is twelve years old, and acts like she is twenty. My parents always get mad at her, but they always give her a second chance and do not ground her. Yet, I get into trouble for the dumbest things. I swear things are unfair around here. She treats me like a child and she and her little friend go into my room and vandalize my stuff. I cannot stand it anymore. She is such a brat.
