Is anyone else struggling to justify to themselves why the fact that is not a cup, but a glass, despite it sharing all the qualities of what you would call a cup were it made of any other material? And doing this simply to assuage the cognitive dissonance of seeing something you have never and would never call a cup, being called one - despite having no tangible reason why it isn't one?

People just use it as "this makes sense to me, therefore it's probably right"

Don't worry, it's just an arrow pointing at the right speed to go through intersections at on the speedometer.
