As a study into teen aggression discovered, parent-child communication and in-class rules dictating how one should deal with others aren't enough. Many teenagers have no real way to express their emotions, to tell people when they are feeling hurt or sad, and basically lash out aggressively as a reaction to those feelings.
在一份青少年的憤怒研究中也發現，父母和孩子的交談，大多侷限在課業上，關於「為人處事方面」的話題相對不足，多數青少年無法具體表達心中的委屈和難過，而直接以憤怒來作為反應。
