Two girls are fighting over an orange. Their mom walks in and hearing that they're fighting over the orange, admonishes them to compromise, cuts the orange in half and gives each half to the girls. But it turns out that one of the girls just wanted the orange and the other the orange skin. They each ended up with half (50%) of what they wanted. So, had they both talked it out, they would have realized it and could have gotten all of what they wanted.
