According to Aristotle, Anybody can become angry. That is easy.
Anger is defined as a strong feeling of displeasure or hostility.
First and foremost, it is important to understand in which style of expression you are engaging. There are several ways in which anger is expressed. They move along as if nothing is wrong and that behavior causes more pent-up feelings that lead to other dysfunctional behaviors such as overeating and drug use. The consequences speak for themselves. Further, we have the passive-aggressive anger.
