One of the classic examples occurs when a couple are going somewhere in their car with one partner driving and the other partner 'navigating' or just giving advice about how best to get to their destination. At the proverbial fork in the road, the driver decides to go left while the other insists that the other way is the 'right' or better way. They get stuck in unanticipated traffic. The non-driving partner becomes angry at the partner driving for having chosen the 'wrong' way to go and, therefore, causing them to become stuck in traffic. "See, I told you we should have gone the other way," he or she screams at the hapless driver. Rather than share the unfortunate development in a "we're in this together" manner, the non-driver now blames the driver for their plight as though he or she committed a terrible offense. This seems to me to be an example of not only needing to be 'right', but punishing the other for having managed to be 'wrong' or, in this case, made a reasonable choice that resulted in frustration and disappointment, but did not deserve anger and condemnation.
