As honest as we all want to be about our financial situations, sometimes a little white lie creeps in every now and then: Maybe you can't afford that dinner your friends are going to, and it's less embarrassing to say you have the flu. Maybe you slightly exaggerate your paycheck to friends in either direction, so no one knows you're the worst paid — or even highest paid — of the bunch. Or maybe you lie to your partner about the shoes you just bought or the amount of debt you've racked up on your credit card.
