Difficulty

So I didn't think it would be this hard to come up with a story for Chase's class. The one we were just assigned to do that is. We have to write a story based on an emotion; mine being, "Enmity". For starters it means hatred and I know it sounds like an easy or simple enough topic to write a story about but I honestly have writers block. I think it's because everything that comes to mind is too cliche; even for me (being the writer). I hope I find some inspiration soon; I would like to get this assignment out of the way.
