Whether it's with a sibling, best friend, or colleague, there comes a time in most of our lives when we find ourselves engaged in a bitter rivalry with another person.

Were you and your rival pitted against each other by a third party? If this occurred a while ago, try and access the emotions you felt when it was all happening to strengthen the scene.
