1) Your teens don’t want you to be their friends. What they need is for you to be a reliable responsible role model worthy of their respect, and not some overgrown child who wears too tight jeans or T-shirts with slogans advocating the good points of 100 proof liquor.

2) Don’t debate the teen ever. If she wants to debate, suggest she sign up for the Debate Club. If you buy into their teen logic (which is basically illogic, the product of an immature brain and every extreme of emotion known to mankind) your mouth will go dry. Teens need to know that no means no. Remember when your teen was two years old and he said “no” a lot? Well now it’s your turn, particularly when your teen wants to engage in behaviors that are dangerous.

3) Don’t buy your teen a car. If you do, he will total it in record time. Guaranteed. The teen should earn the car, or at least a portion of it (and by that I don’t mean one of the tires). You know how you take much better care of an item of clothing you spent a fortune on compared to one you bought in a bargain basement? It’s the same thing, only a car can do serious damage.

4) Encourage sports participation even if your teen has two left feet. In some sports, two left feet won’t knock him out of the box, so to speak. Sports participation develops perseverance and cheerfully functioning as a team member. You also will know where your child is every day after school (on the field, that is, or at a rival school). Just make sure you root for the right team, okay? Been there, done that.

5) Let the school know you in a good way so that school personnel do not dive under the desk when you approach. If you are asked to speak at the school, your teen will feel mighty proud. If you make something for the bake sale, try to make it taste edible and if you can’t see it through, do yourself and your child a favor and buy something at the local bakery or supermarket.

6) To know your teens’ friends is to know your teens. Teens have a secret life, and a parent’s goal is to find out secrecy that is sometimes thicker than the CIA and the KGB combined. If you really want to know what your kid is up to, get to know their friends. How? By being warm and kind, and by asking questions that don’t sound like an interrogation（审讯）, but serve that purpose without their knowing it.
