-Laugh at everything they say, particularly when they are wearing a straight face or are crying.
-Don't take them anywhere they want to go; you need your rest.
Forget the fact that 10 years from now your evening of rest will have not meant a thing, but they will remember that you never would take them anywhere they wanted to go.
-Don't take their relationships seriously.
You know they're only temporary anyway and teens' feelings are always so blown out of proportion.
Be sure to forget the fact that they learn about relationships during these critical years: particularly their relationship with you as their parent.
<-Tune them out if they drone on and on during an important episode of your favorite show or during a movie of the week.
TV is way more important than listening to your child.
-Don't trouble yourself with learning about their friends.
Teens are really irritating anyway.
-Be sure to punish them just for the principle of it;
forget about the fact that most of that *$@?*^ is just small stuff. Sweat it anyway.
-Don't beat yourself up when they say "You never listen to me."
Afterall, they're right.
-When you're fighting with your teen, act just as immature as they are;
how else will they learn how to fight with their loved ones?
More later. I'm sure there are many more "ways to alienate your teen and wound their spirit"
