K-keep on the topic, don't dig up old grudges. Not all anger is bad . Lastly, after all these warnings, suggestions, and methods for controlling anger, I must underscore that although anger is unpleasant and potentially dangerous, it is often a beneficial and commendable emotion. When that is so, if properly controlled, anger is a reasonable and effective reaction to an unfair or offensive situation. Specifically, anger motivates us to do something.
Anger discloses unpleasant truths to others.
Anger communicates that we are upset, that we can and will express ourselves, and that we are determined to correct a bad situation. Anger can over-ride our fears that keep us withdrawn and compliant. Anger, properly utilized, gives us a sense of pride when we exert some control and improve a bad situation. Non-violent anger used to right wrongs is no vice, it is a virtue.
