This is a personal question, which means that only you can answer it accurately. However, this is an example of a possible answer:
I once faced a conflict that involved my two sisters. The two of them disagreed about who should keep the nicer room after we had moved in into a new house. Both of them wanted to have the room with the biggest windows, as these faced the ocean. The way in which I solved the conflict was by acting as a mediator. A mediator is a third party that helps solve a conflict through communication and negotiation. In the end, we reached a compromise by one of my sisters keeping the large room with big windows, but having to give the large, fluffy rug she liked to my other sister. Everyone was satisfied.
