We were promised a twist, but this ending was telegraphed from the start, especially given how short the story is.
As the ending had been telegraphed far from the end of the story, I expected the twist to be the one from an old Country and Western song in which the same situation developed, except the added twist at the end, that the girl's father wasn't her physical father, as the mother had also had a lover who was the girl's father.
This was perhaps the biggest waste of my time on this site in awhile. no character development no was compelling plot just to drive recitation of a bland story.
Perhaps the twist was that the obvious twist did not save them and allow them to come up with children. One thought is that they should have done the DNA work in order to see if there were any dangerous recessives. Otherwise the child would only have the good genes reinforced.
The twist was obvious, however, If this is how the so-called "upper class" lived, I glad I wasn't born that way.
