Since perspective is subjective and should not be argued as fact, refuse to tolerate someone being cruel in their delivery of what they FEEL is honesty. However, be aware that if people are made to walk on eggshells to preserve your ego, the act of lying is much faster to pacify any potential arguments. You can train someone to be brutally honest by owning insecurities that build defense mechanisms to react negatively to constructive criticism. With a good self-worth, you will learn your truth is yours and anything else outside of it either teaches or is discarded for irrelevance. You can easily train people to lie to you if you have a hard time accepting exterior perceptions, even if irrelevant.
