In one of my readings i found an article that give helpful tips so i'm posting it here. This is excerpted from the book How to Speak Alien by Michael Ross.
Nine Keys to Connecting With Your Teen
1. Trust earns you the right to be heard. Isn't "your right" already guaranteed simply because you're a parent? It should be, but in the real world it isn't. Your teens are focused on the here and now. They're probably not thinking about all the sacrifices you've made for them through the years or even how much you love them. But they will, almost instantaneously, recall the "injustices" you've caused: your "countless" broken promises, the times you blamed them for things they insisted they didn't do, days when you were "too busy." While perfect parenthood should never be your goal, it is important to build trust by earning the right to be heard.
2. Your attention builds trust. Teens know that love shown by parents says, "Your life is important, daughter (or son), and I'm going to give you my time." Spend time with them, show them you will listen and talk and work things out together. Invade their world ... and let them invade yours.
3. Breathing room = trust. Invading their world should be balanced with plenty of space. Invading their world doesn't mean you continually nose into their business. Teens need room to grow, to make their own decisions. This is crucial for their development into responsible adults.
4. Watch what you say and how you say it. The best intentions in the world can backfire if you use the wrong words. Phrases like "You never," "You always," "You don't ever" sound accusing and can cause your teen to become defensive and ultimately to shut down. When you speak, stress your particular wants and feelings by using "I." For example, saying, "I want" or "I feel" are effective places to begin.
5. Take interest in what your teen has to say. A few years back, a TV talk show on parent-teen relations confirmed the need for parents to take a stronger interest in their kids. Teen after teen shared stories of heartache about life at home with parents who were out of touch with their kids. As the show ended, the host asked the audience for their comments. A 14-year-old boy stood with his mother and shared these words with a national TV audience: "This is my mom. She knows me." You can close the gap by taking a genuine interest in your teen and his or her world. Tune into feelings and try to look at events at home or at school from your teen's point of view, as well as your own. If your teen senses that you don't really understand or care, he or she will stop listening to you. But when you're clearly doing your best to understand, the chances are much greater that your teen will tune in to you.
6. Learn to listen. One of the biggest complaints I've heard from teenagers is that their parents just don't listen. "My parents don't understand me." "We can't seem to communicate." "Things could be better if they'd just give me a chance - and listen!".
7. Control your anger. Many parents fail to acknowledge the extent of their anger. What's more, the parents expect their teenager to exhibit a maturity level that he or she has not yet attained. A father may harshly command his teen, "You will not speak to me that way. That is disrespectful, and I won't put up with it." The teen walks away and the father has "won" the argument. Yet the father has exhibited the very behavior that he does not allow his teen to show.
Listening is the only constructive way to process anger. As you become a better listener, your teen will begin to feel understood. He or she may not agree with you but will respect you because you have treated him or her as a person. Your teen will be more inclined to follow your leadership.
8. Be flexible. It's easy to approach your teens with tunnel vision. You know what you want and that's all you see. Unfortunately, tunnel vision will make you completely unaware of the needs of your teen. And that's how many family arguments get started - with people screaming demands at each other, blind to the needs of the others involved.
9. Make "shared meaning" your goal. If you're tired of pointless arguments with your teenager that never seem to accomplish anything - except maybe your blood pressure rising and him or her being grounded - try a communication style called shared meaning. The goal of shared meaning is to be heard accurately. And once you've had a chance to state your case and listen to your teen's perspective, the foundation is set for communication - and for a fair solution to what's bugging you.
