You can role play how a teenager can handle a situation. For example, help a boy to know what to say, without sounding like a nerd, when his buddies want to go to a party he thinks is questionable.

It is like writing a book with illustrations on the tablet of their minds and hearts. It won't fail.
Parents do write books in the minds of their children.
