In teenage, this behavior is very common. It can be due to their inability to express their fear, frustration or any kind of rejection. This behavior can be learned or acquired from elders. These kids don’t have any idea that the immaturity they show can affect the relations in long run.
On the other hand, assertiveness can be defined as respectfully demanding ones rights. These teenagers need to learn the difference between real aggression and being assertive. The one who is assertive is always willing to discuss or compromise or even negotiate and wait while others think about their demands.
People should learn how to communicate their needs, feelings and beliefs with others. One should have a proper body language. He should look straight into people’s eyes, the body should be held upright ie. no slouching at all, shoulders should be relaxed and there should be proper breathing.
When a person becomes aggressive, he loses the control over any given situation. On the other hand, assertiveness helps you to put your point in a proper way that can be accepted easily
