When brainstorming for your scene, consider these questions:
-Do you want to include any other characters? Could there be another character who has some stake in the fight who is just in the other room?
-Has this fight been brewing for a long time or was it triggered by a recent event?
-Do you want the tone of your scene to be comical, tense, tragic, or a mixture of these elements?
-What is the relationship between your characters? Are they dating, family, friends, or even strangers?
-Why do they have to be quiet? What will happen if someone hears what they are arguing about?
