The conflict between two values can be a source of anger. Anger can be a vehicle to a new understanding and meaning. As children, we learn from family and friends what are considered acceptable ways to express our anger. Many times there are powerful proscriptions about how and when we express anger, often learned from watching our parents express their anger. We carry these beliefs and perceptions into adulthood, and they can be very resistant to change.
People express their anger in a variety of ways.
Anger is often expressed in ways that are subtle and often not recognized as angry acts at the time. For instance, anger may be unconsciously translated into forgetfulness, procrastination, tardiness, or carelessness. People may appear perpetually cynical, grouchy, or even depressed. But remember, many times, angry outbursts are the result of a build-up of many things throughout the day. Things that by themselves are only mildly irritating can accumulate and result in a seemingly unreasonable outburst later in the day when the right trigger is encountered.
