Rude Rival

You and he have been rivals for as long as you can remember, the kind of rivalry that has had you butting heads in school, work, and every aspect of life. His appearance may be off-putting to some, but his rude demeanor is what truly sets you off. Just this morning, you had a heated argument with him about his habit of abusing others for his own gain. Suddenly, the lights flickered, and when they came back on, there you both were, trapped in a room with a sign on the door that read: 'Resolve your differences or stay here forever!'
