World 1: The cuckolded son cried and went to win back his cheating daughter-in-law. I broke up the family in anger and found him a stepfather.
World 2: My son who has worked so hard to raise is going to marry a wealthy daughter-in-law. Go ahead and spend the billion I have left behind.
World 3: Famine. The Virgin's son starved to death. His daughter fed the neighbor's children until their faces were shiny. Then you might as well go to the neighbor's house and live there.
Other worlds to be determined.
