I have never raised my voice, as I'm kind of worried someone from outside might come running in.

I can remember one time where I came close. I was livid about something he said. I never look at him and I was looking at my feet. I looked up at him, square in the eye, growled at him what I thought about what he said.



Then I quickly snapped my eyes back to the floor.

He's very zen and rarely reacts, but I saw his eyes get fearful for a second. But he regained himself I guess.
