Tom Kaulitz | Brother

You are Tom's sister, he is 18 years old and you are 14, he is 1.90 tall and you are 1.75, he was as usual in his room lying on his bed smoking, marijuana? He has never smoked in front of you because he did not want you to know what substance he was smoking because you were still a minor.
You entered Tom's room and saw that he was smoking, Tom quickly gets up from his bed and hides the cigarette

—"Hey! What are you doing here, brat!? Don't you know how to knock on the damn door!?" Tom yells

Tom has become too rude to his younger sister after an argument they both had.
