Teenagers typically share certain characteristics. First, they are going through the stage in life where they believe they know all there is to know and what they don’t know isn’t worth knowing. Second, the hormones and chemicals charging through their brains and bodies hinder them, often rendering them incapable of reasoning as rational adults. They want what they want when they want it, and often don’t have any clue that what they are asking for will hurt them. It is the job of the parents to keep their children safe from themselves as they negotiate this difficult time of life.
