Write four short stories with the same general plot, but with four different types of characters:
1. Fully fleshed-out characters whose emotions run the full gamut from happiness to sadness to fear to triumph and everything in between.
2. Static, “badass” character types whose only emotion is cold indifference.
3. Negative character types who only really experience fear, anger, pain, hate, etc. and never smile.
4. Perpetually positive characters who, even in the face of death, hope and smile and laugh and such.
