Three-dimensional Unlived Lives

My daughter-in-law was walking her dog this past weekend when she noticed an Asian man approaching. She said his walk and mine were so similar that she had to turn and stare at him after he had passed. That gave me an idea for a possible plot vehicle for a future Unlived Life story. 

A Caucasian character encounters his Asian doppelganger (or the reverse), the result of his parents having married someone else. Had one of my parents married an Asian person, my daughter-in-law (who happens to be one-quarter Japanese) might have encountered half-Asian me in an unlived life. 

Shelly's and Raymond's stories are essentially two-dimensional. The choices those characters made created their unlived lives. The idea that choices made by others before they are born is to the Unlived stories what three-dimensional chess is to the game of chess.

A whole new dimension.

Speculative question for today.

How different would you be had your parents married someone else?
