"Nigel is always right" is a fucking in-joke, FFS. I'm always right the way a fifteen-year-old is always rational.
And shit, yeah, sometimes people need to stop and wonder whether maybe, just MAYBE they're wrong because they're missing part of the picture. It can be a startling thought, if you open yourself up to it, to consider that something you have been taking for granted as TRUE may be seen as FALSE by people who are more affected by it than you are. It may even take a moment of pause, some reflection, and a little flexibility of intellect.
To judge someone's inner process based on a few brief outward expressions is, IMO, pure arrogance.
