Speak as Rachel
Speak as Tony
Tony: I'm preparing for my final exam.
Rachel: Can I watch TV here?
Tony: No. I need to study.
Rachel: Do you want me to help you study?
Tony: No. I just need you to leave me alone so I can study in peace.
Rachel: Do you want me to get you some food?
Tony: No. Beat it.
Rachel: That's rude.
Tony: Seriously, stop bothering me, Rachel.
Rachel: I'm just trying to help.
Tony: You are the most annoying roommate I've ever had.
