we are all liars.

those who claim never to speak anything other than the truth, are the biggest liars of the lot.
we lie to others ("oh, I'm fine. how are you?").
we lie to ourselves ("i won't break my diet.")
and we lie whenever we insist that we know the truth.

in reality, none of us can never know precisely what that is.

even so, some lies are much bigger, more insidious and dangerous than others.
