They both were functional but somewhat strange.
She processed puzzles differently than most.
And he missed conversational exchange
(he smiled but would fail to thank a host).
Yet he, in natural bent to engineer
and she, abrim most days with earnest thought,
communicated well, by eye and ear.
They mated, married, worked for what they sought.

With every fresh idea she would suggest,
he heard and told her if it could be built.
They prospered so for half a score of years.
But he grew old in mind, and she grew stressed.
Her boredom bloomed, and his depression spilt.
They cancelled out the music of their spheres.
