Anger is a negative emotion that only a few can claim immunity from. Although, it's very normal to get angry, anger becomes "very negative" when it causes damage to people and things.
When angry, you may blow off steam by screaming and bellowing to let the other person know just how upset you are, and if I may say so, screaming can make you feel understandably "more powerful than the other person and more in control."
However, the problem with speaking in anger, is that you hurt people more than they deserve especially when angry with a loved one; saying things you wish you could take back. Sadly, hurtful words spoken can leave a scar on the heart, even with forgiveness. Just think of it, more problems result from anger than solutions; look at the wars all over the world.
When next you are angry, speak calmly or summon the strength to walk away. Remember, it is not a drama scene, you don't have to prove how angry you are; just calmly state your case or mind.
Above all, nothing speaks louder than silence. From experience, you actually win when you ignore an annoying person, you say neither too much nor too little to regret.
A wise man said, "Do not argue with fools because, people from a distance can't tell who is who."
"There is no revenge like oblivion, for it's the entombment of the unworthy in the dust of their own nothingness"-Baltasar Gracian 1601-1658
