Lies stem from insecurity. The person lying to us is insecure. They are worried about losing face or getting punished for doing something wrong. They are lying to smooth things over, to avoid confrontation, and to cover their inadequacies.
Of course, lies hurt. One would be foolish not to acknowledge that. But at the same time, truth can hurt too. Would we prefer facing a painful truth to a smooth lie? Most of us falter at this question.
Once we know the person telling lies is insecure, how can we not comfort them? We hold the key to how we react.
