The life trajectory of a son or daughter is no natural arc. More like a maze. Even so, the ideal model of child and parent relationship is traditionally plotted as linear. Education begins at birth. Parents teach us the basics. How to communicate. How to walk upright. From our parents, we learn hot and cold, right and wrong, yes and no. It’s not all binary and didactic though. A large portion of what we learn is at the tacit level. Year after year, this tacit knowledge takes root in that deep space within us where the words to describe what we know often evade us.
