Miscommunication sometimes leads to arguments, and arguments sometimes lead to fights. Anger is usually present in arguments and fights. Anger is an emotion, usually classified as a negative emotion. Negative emotions can cause severe problems in our environment and to the health of our body. Happiness, usually classified as a positive emotion, can bring good health to our body, and spread positive vibrations into our environment. Sometimes when we are ill, we are not on our best behavior.
