Thanks Denis
Also key is, I am (and you are) sometimes the difficult person.
I have neutralized this probability by making sure that I am never, and I mean NEVER, the interfering party. I have "psychologially retired" and do not interfere in other people affairs . And the people and situations I am here to learn to deal with are when someone else comes to me, and forces me into some kind of a problem. Or someone who creates, messes up a problem very close to me, and I see myself in the middle of it against my own will.
In such cases it doesn't matter, IMHO, what kind of person I am. It is someone else who created the confrontation by forcing me into something I don't want to be part of.
Take the example of our supervisor who had to deal with a very baaaaad manager. Without my knowlege he put my name as the "expert" on something, and suddenly I saw myself in the middle of a mess between a dictatorial & moody manager, a belwildered team, and a "do it yesterday" type situation. I did the job the best I could, then smashed my supervisor, and made sure he doesn't do that again.
In that situation, I didn't spend anytime analysing him and his frequent wrong decisions, or the best way to deal with him and his mistakes. I just blew up with anger. It works, but it hurts too. We are not young anymore. We are getting older and looking for peaceful quiet times.
Also, trying to make these people understand helps them to do the right thing in the future, not because they fear someone might get angry, but because they start to understand why their previous behavior was wrong.
