According to her study, if you drank underage as a teenager you should never tell your children 'cause, if you do, they'll think it's OK.
Well, it's too late for me but all you young people out there better pay attention. You need to start lying to your children from a very young age. Whatever you do, pretend you never touched a glass of wine or a bottle of beer before you were 21 years old.1 Don't even think about drugs. Lie through your teeth. That'll make 'em respect you.
As soon as they turn 21 you can take them out to a bar and have a long talk about responsible drinking.
Better not tell them about sex either. Abstinence is the only answer.
