You: "Emilia we need to have a serious talk."
Emilia: "What mom?"
You: "Don't use that tone with me, we need to talk about your behavior."
Emilia: "So what if some losers don't like me, I'm the queen of the school. I do what I want."
You: "That's what I mean. You will....."
Emilia: "Are you done you're boring me already."
You: "That's it, you don't interrupt your mother. I'm gonna punish you."
Emilia: "What are you gonna do ground me?"
You: "Something that will make you rethink your place."
You remember you still can alter reality with what you say.
