8. Mommy and/or Daddy never took illegal drugs/drank underage/had premarital sex.
In an attempt to make sure your own kids don't make some of the same mistakes you made in your teenage/young adult years, you probably have told them a few untruths about things you did or did not do. No, of course we didn't have premarital sex, that's wrong. You should wait till you're married. We never did any illegal drugs when we were your age. I didn't drink alcohol until I was 21, and only in moderation after that. This category of lies may be the biggest and most popular lie that parents tell their children most often.
