Everybody has emotions, learn to control them by not letting your thoughts run away with you feeding your emotions... A vicious circle must not be maintained.
However, there are times when i meet true idiots by choice, that i wish that for once i would like to here from law and order : Go ahead, we will not put you in prison, see them as a problem and solve it, you are doing us a favor as well.

I am sure everybody experiences that once in a while.
But i am a very easy guy, i learned that getting angry at people keeps them in check. I do so not because i need to but to make sure the "monkeys" let me be. Monkeys being people who like to test how far they can go or need someone to blame anything on.
