everyone's a liar

We all stretch the truth and tell lies by omission. Just getting along with people involves both. Humans are hardwired to deceive. We deceive when we’re competing with other members of the same sex; we deceive when we’re trying to attract the other sex. Deception is more the state of nature than not deceiving. In the animal kingdom, virtually every species deceives all the time. Why don’t we lie even more? It helps our reputation for people to know they can believe us.
