Using someone’s anger as a measuring tool to evaluate them is a fascinating idea.
Some people behave like a 2-year-old throwing a tantrum. Nearly anything can touch them off.
You would have trouble with me. Very few things make me angry.
In one instance, my trainee said that it was the only time she saw me angry about something. I never said anything. A co-worker was intentionally doing a bad job that would damage our customers and refused to fix it.
If something does happen, I can ignore it, talk about it a bit with an impartial person, or do something about it.
Whatever happens, I will not throw a tantrum.
If I do something, it will be based on cold analytics, not emotions.
