I (Dr. John Townsend) have talked to many young adults who have told me, “When I was a teenager, I acted like my parents had nothing to say to me. I couldn’t afford to act differently. But inside, it mattered a lot what they said.” You can’t predict how telling the truth and establishing healthy boundaries will affect a teen, nor can you predict when the change will occur. I have seen parents with a seventeen-year-old who would be moving out in a few weeks still make significant inroads with a rebellious and destructive attitude. . . .
