William, depositing goodwill is extremely helpful and can save someone's butt when they make a mistake. However, I also believe that individuals should view others, who may be going through various emotional states, with eyes of love and acceptance. Not everyone can or is willing to do that. Most people operate on a "tit for tat" basis or are simply takers. The best way to handle individuals who occasionally lose control is to approach them with calmness and diplomacy, understanding that they might have little control over their reactions.
