How do you cope up with people who have anger issues in their attitude?
Do you retaliate resulting in violence? Do you ignore the person? Or do you communicate with the person and try to fix their issues?
I think it is best to let them know first about the issue that they have, that way they'll be aware that they have that kind of problem. When it comes to dealing with people like them, it is also best to not stoop down to their level to avoid conflict and misunderstanding, just leave them be and let them cool for a while.
