Honesty Is The Best Policy
Even though we live in a world where honesty is a rare trait it should be noted that the old adage of honesty being the best policy still applies. If the entire family of human beings followed this policy on a daily basis the world would be a better place to live.
Being honest however is not always an easy thing to do. It requires effort and commitment. A person can be successful at being honest if they apply a basic principle that has been around for a long time. However you want people to treat you, treat them the same way.
