Again, let's think of two children fighting over their shares of a cookie. Child A says he should get all of the cookie. Child B says that wouldn't be fair, the cookie should be split evenly, half and half.
The adult in the room decides to promote common ground, and gives 75% of the cookie to A and 25% to B.
