I'll tell you what, I've taught for years, and one very common need from teenagers is that they want adults, especially their parents, to talk openly to them by being respectful and honest. Teenagers really feel "part of the communication process not just an "object" getting screamed at or down to.
If you notice positive qualities and behaviors that your teen has shown, praise them, they will respond in their way, but it will warm their heart even if they don't admit it in front of you.
My great parents, I want you to realize, I'm not saying that teens can't be tough and very difficult, sometimes even day to day, however, if they realize that their folks are being fair, honest, and respectful the Parent/Teen relationship will take a energizing and positive spin. Coach Anthony
