But in the real world, you couldn’t really just split a family down the middle, mom on one side, dad the other, with the child equally divided between. It was like when you ripped a piece of paper into two: no matter how you tried, the seams never fit exactly right again. It was what you couldn’t see, those tiniest of pieces, that were lost in the severing, and their absence kept everything from being complete.
