Anger can be so self-destructive, not to mention harmful to others around you as this nurse learned.
I think of the few times my wife and I got into a real argument. Each of those times, I left the house to take a long walk or a long drive (though a peaceful drive - not tearing through neighborhoods like this nurse). When I came back, my head was cleared and I was ready to work things out in a civil manner.
My wife would criticize me for that behavior, like I was "running away" from a fight. Actually I was. And I likely prevented myself from doing or saying something I would regret for the rest of my life.
Same with potential road rage incidents. When I get a jerk tailgating me or otherwise driving in an offensive manner, I just pull over and let the person go around me. Just not worth it.

I know by experience that some remarks can never be unsaid, whether one apologizes or not.
