Anger is manageable, but it takes effort and practice to change the wiring we have gotten used to using. I go from happy to are you FN kidding me to Go F ur’self in 3 seconds if I let it happen. If I catch it happening I can take a deep breath and think of a better way, with my wife I tend to not be as careful and that is an issue and something else I’m working on.
