Thanks Mike
I liken your suggestion to my teaching days.
I never mastered it myself, but colleagues said “act angry and grumpy with students in the first 2 months,after that you can relax”.

So what you mean is, use fake anger, pretend you are angry in minor issues before they become full-blown problems and you have to use real anger?(then it is too late and you are out of control)
Shame we have to do this but I take your point and it is a very good one.
I need to practice my temper tantrum, (spit the dummy) performance in the mirror. 🙂
