People never listen to teenagers. Most people don't trust us because they say it's the time in your life when you go through the emotions or as many people turn to drugs and smoking during their teenage years. They are rarely given the chance to speak their thoughts and its wrong.
I don't believe teens are denied freedom of expressions. They already say their opinions out loud on the internet and they can't really hide their emotions in reality forever. I have seen teens before and they really like to act crazy and youthful around their friends. Also, if they need to let their feelings out or something then they could just talk to their friends, family, or teachers.
