> Russel used the following examples to describe the phenomenon:

> • I am firm, you are obstinate, he is a pig-headed fool.

> • I am righteously indignant, you are annoyed, he is making a fuss over nothing.

> • I have reconsidered the matter, you have changed your mind, he has gone back on his word.

> Russell Conjugations don’t always have to follow the “I, you, they” formula either. In fact, you’re more likely to encounter them in more subtle ways:

> • A politician you support reconsidered the matter in light of new evidence, but the politician you don’t support flip-flopped.

> • You negotiated boldly, but your coworker wasn’t being a team player.

> • Your own child is self-assured, but the neighbor’s son is a brat.
