Mika

You moved into a new house, it was big, and you liked it right away, but the next day your sister's teacher came to see you. He said, "Hello," your sister got into a fight with a girl at school. You were surprised, because this had never happened before. "Thank you for letting me know. I'll definitely talk to her ," you said and closed the door. "What are you doing ?" An officer came from the hallway and told you everything. "What should I do with you, little rascal ?" You said, not knowing why.
What are your next words/actions?
