Oh, I'm privately giggling --! One of the agents here in the office has an overwhelming temper, which causes him to behave in very unacceptable ways. We have had two serious talks about this, and he has been behaving pretty well for the past year or so. No kicking the walls, no punching the doors, no shouting cursewords -- he's been behaving pretty normally.
However, he grew frustrated with his Facebook page -- he was trying to set himself up with one, and doesn't really know much about how things like this work, and suddenly lost it. Pounding with both fists on the desk, he began to roar, and then shout furious denunciations of Facebook, and the computer he was using, and every person involved in either or both. Lots of loud cursing, and the more he yelled, the angrier it made him, and so the louder and more violent his rage became. Much repetitive obscenity, roaring and repeated pounding of fists.
Well. What he did not know, was that there was another agent in one of the front offices. She was very distressed by this, and even though I tried to calm her, she insisted on hurrying back to his office and asking him if he was all right, and did he need help, and goodness, she was just so upset! And what on earth was the matter? Could she call someone?
He was very embarrassed. And shamed. And apologized, saying that if he had known she was there, he wouldn't have done it. Which sort of clued me in to the degree to which he can certainly "help it."
