I belong to some tribe of people, living in the wilderness. Another tribe comes from the hills, and moves into our area. When they first come, we are uncomfortable with their presence, and it looks like we may go to war with them, and some may die. There is a lot of tension, but before long, we settle in. They take an area adjacent to ours, we give up a little space, and we agree on a line of demarcation.

Then they declare ownership of an old run-down barn which is apparently not clearly in our territory or theirs, but we consider it our barn. What are we going to do about that? The situation gets tense again.
