Somewhat Daily Dose of Wow! 11 Apr 11 Who Are We Lying To?

I remember my father telling me, more than once because I was such an obstinate child, that when you tell a lie you must tell three more to cover that one up, and they just keep growing "until pretty soon, you're caught."  It occurred to me this morning that we've already lied to ourselves several times before we've uttered the first lie out loud. Sure wish I knew why we do that.
