One of the worst things that can happen when someone gets angry is for them to say something they regret. It happens all the time. They become overwhelmed with anger and their desire for revenge overtakes everything else. Boom, they say something cruel or hurtful that can’t be taken back.
It’s a difficult thing to do but people need to find a way to stop, think through how they are feeling and how the other person is feeling, and then decide if and how they want to respond. Learning to do that can be the difference between letting your anger get the best of you and using your anger in a positive way.
