For example, the challenge could be for stories about 'angry revenge', or 'hesitant confession', or just simple broad topics of 'loneliness', 'frustration', or 'compulsion'?
Interesting idea, KD, but I'd agree, it might feel rather constricting to write. Even worse, the entries might become monotonous to read. I like the way the challenges we've had so far have all allowed for a huge range of approaches, moods and styles.
