In flying we react in an emergency as we first learned to react. When we show anger we react as we first learned to react. Just as understanding an aircraft emergency will enable us to cope with it, so will a better understanding of anger help to defuse it. Almost any situation or delay can become an invitation for you to become angry. You are not required to accept the invitation. You may accept the invitation and become angry or you chose to ignore it. It didn't happen. You can intellectually reduce the 'sting' by assuming that you were not the target of the invitation in the first place. Skill in flying will improve most anyone's emotional stability.
