That I am a man and not a woman can be verified, but if I were to say I was a woman, and then tried to explain the error by saying I hadn't checked the statement, the explanation would not be accepted.
Okay, maybe you don’t have strong beliefs about the “right” way to load a dishwasher, or about your sweetheart’s propensity to do it “wrong.” In that case, either you are unusually saintly or (like me) you don’t own a dishwasher. But you almost certainly get involved in domestic disputes about who’s right and who’s wrong all the time; we all do. Although interpersonal arguments can have a number of causes – from serious and painful breaches in trust to the fact that we haven’t had our coffee yet – an impressive number of them amount to a tug-of-war over who possesses the truth. We fight over the right to be right.
