From your own personal experience at home, work, school, neighbors, friends, extended family, etc., explain an actual dispute that occurred and who was involved. Note that you do not have to be in the middle of this dispute, but you should have knowledge of the particulars.
After explaining the nature of the dispute and who was involved, explain how the dispute was resolved or not resolved. Was there anyone who attempted to mediate or influence this dispute? If so, how did their “getting in the middle” help or not help?
Finally, looking back at the situation after time has elapsed, how might a more skilled mediator have been of assistance? What could have been handled differently, and how should it have been handled in your opinion?
