Some people have an event like this and never talk about it again. Then they continue to wonder why the same thing happens over and over again. They give up being right and instead choose a happier path. If problems are not discussed and responsibility acknowledged by each partner for their share of the problem, then the next time one of those small, insignificant everyday misunderstandings occur, the same stuff is likely to surface. Often the conversation about the event goes like this.
Anger distorts our ability to interpret accurately.
You both experienced the same event but each scored the event differently. When this happens, rarely do we consider our partner's position. We dig in to protect our turf. This is a deadly game for relationships. People who really love each other do not practice this kind of destructive score settling.
