Why Do People Get Mad And Yell And Act Mean?

All the three forms of behaviour mentioned above is the result of frustration. Frustration happens when you expect something and what you aspire is either little or not according your standard of acceptance. So in order to vent out the frustration, or voice their displeasure, people either raise their voice by yelling or getting mad, or they simple ignore you or speak indifferently. The latter is a form of mean behaviour.

However getting mad, yelling or being means does not quite solve a problem. Well, it may do so temporarily but in the end, it does not prove to be productive. The one who is the object of ridicule or anger shuns relationship with the person who is angry. Slowly and surely, such a person will keep off from the angry person and back-bite about her, retaliate or even make plans to destroy her. Self-esteem is important for everybody and by yelling or getting angry, you are only disturbing a person's ego.

I don't know but it is destructive to both the person being yelled at and to the one doing the yelling. Unfortunately, getting mad is part of the human experience. Bad things happen and people get frustrated.
     Taking it out on the people around them is a personal choice. It only makes things worse. What can I say people are stupid; they don't think when they are mad.

Because thats the way a lot of ppl deal with stress instead of maintaining self control. Some ppl just havnt learned how to control their emotions and deal with life situations with positivity.

For me it is a breaking point. I get so frustrated with the way things are going, then either something else happens or I'm tired and the dam breaks and I yell. Usually at the ones you love. Even at myself. You feel so bad cause it not only hurts the other person terrible but it hurts you.
