Connection deepens when exchange can move in more than one direction without becoming an accounting system.
Connection deepens when exchange does not have to be perfectly symmetrical at every moment.
A friend may carry more during illness. A parent gives differently from a child. Communities contain changing needs.
Reciprocity is therefore not accounting.
It is the larger expectation that relationship contains movement, responsiveness and mutual recognition over time.
That is what lets Connection remain alive rather than becoming extraction.
