Nobody likes a liar. We all make mistakes. We all change our minds. Accept your past and move on. When someone accuses you of smoking pot your response should be “So what?” We all go through a growing and learning process. We learn from our mistakes. Lying about little things is not an attractive attribute.
To the Democrats: Campaign on the premise that you are more aware and smarter after having “Overcome” some less than wise decisions in your life. Remind them that this is called LEARNING!!! DO NOT APOLOGIZE! Stop letting them treat you like children. Admit it, say that you have learned from it, say that you are a better person for it and MOVE ON!
