I once had a totally commonplace, uneventful thought that transformed the way I viewed relationships.
I’m not sure that it was mine; it certainly wasn’t anything groundbreaking or unique. I may have read it somewhere, I can’t remember now.
It was the notion that when two people in a relationship think of themselves as on the same team, things get much easier. Positive feelings grow freely. Score-keeping and resentment are nonexistent.
