How to Discipline a Lying Teenager
Teens might lie to avoid punishment for misdeeds or substandard performance, to be allowed to engage in certain activities or even to cover up another lie. This does not mean you are a bad parent or your child is a bad person. What it means is that teen lying is a normal part of growing up. Even though you cannot prevent all adolescent prevaricating, you can render the results distasteful for your teen. You must take this behavior seriously. Refuse to tolerate the lying and discourage its progression with appropriate discipline.
