How they think
Tracks the dozen small things that keep the big thing alive. Memory for who needs what and when. Skeptical of plans that ignore the logistics which make plans happen.
In relationships
Love looks like the dinner remembered, the errand done, the problem anticipated before you noticed it. Needs a partner who sees the invisible labour and names it out loud, because he won't.
