I'm going to flip out at a coworker
Why do you think that you are so angry at them?
He said something offensive on the car and for that I kicked his ass
It's okay to get angry; you can't control that. What you CAN control is letting that anger make you do things that can put you in jail.
I'm going to show him who he's dealing with. I've won over worse guys.
I think that you should try to control yourself. I think that it is okay to get upset with a coworker, however it is not okay to lose complete control.
