"In mathematics, a distance function or metric is a generalization of the concept of physical distance. A metric is a function that behaves according to a specific set of rules, and provides a concrete way of describing what it means for elements of some space to be "close to" or "far away from" each other".
In life, there is such function. No rules. No concrete way of describing what it means for people to be "close to" or "far away from" each other.
I am close to you and far away from you, in the same breath. How amazing and wonderful is that?
“Out beyond ideas of wrongdoing
and rightdoing there is a field.
I'll meet you there.
When the soul lies down in that grass
the world is too full to talk about.”
