Are there some days you feel like you and your teen speak different languages? You say something simple and maybe even nice to your teen (at least you think it's nice) but the response you get is completely incomprehensible. Let me explain how that might happen.
The first disconnect is that adults live in a thinking brain, and teens live in a feeling brain. And I mean that literally. Brain research has shown that when teens and adults are shown the exact same photo of a human face expressing an emotion, their brains respond in very different ways. An adult brain uses the frontal cortex (the thinking brain) to interpret the emotion, and the the teen brain uses the amygdala (the emotional center of the brain) to interpret emotion. This is a set-up for constant miscommunication between teens and parents. Teens literally see things in the human face that adults don't see, and hear things in human voices that adults don't hear. It's kind of like dogs that hear the high pitch sounds that no human can hear. Dogs...teens..
I am sure you have had the experience of saying something to your teen in a neutral voice and with a neutral expression. It may be something very inconsequential. But the reaction you get from your teen is crazy! Maybe something like "are you mad at me? They have heard something in your voice or saw something in your face that no one else apparently can see or hear...just like the dog.
A compounding problem is that teens carry every teeny tiny emotional experience that has happened to them over the course of their day in that amygdala of theirs. Perhaps they said something embarrassing in class and their fellow students laughed at them. Park it! Maybe they tripped in the hallway at school and felt like everyone saw it. Park it! Maybe they saw their crush talk to another boy/girl and feel dejected. A thousand things may have happened that day, or in the morning between when they woke up and you pass each other in the kitchen before school. Basically their parking lot of a brain is always full. You know how frustrated you get when there is no place to park. Times that by a hundred, and that is your teen.
So when you get a response to a simple question or comment that seems crazy and completely incomprehensible, assume that their parking lot is full. Probably best to just walk away with a let's talk later. This is one of those times that it just isn't about you.
