If anyone disturb me when I concentrating on my work then I get angry. Actually angry is the human's nature.
Anger Creates more problem than solve it so I don't show it on my face rather than it I try to solve problem that makes me angry.
When someone does something wrong and doesn't accept it, it makes me angry.
If I failed in this interview this makes me angry (with smile).
Getting angry is the humans nature. But controlling that is the key to success. I also get angry when any one under estimate me then I will show my anger with my success not in my words.
