lol! right? you clearly get angry over tearful. apparently this is more threatening to witnesses as a means of 'this is what happens when you cross me'.
I go from 0 to 60 in seconds flat, and back again. If I'm confronted by a stranger, I am very aggressive, and occasionally use such incidents as an excuse to pick a fight. I never back down. If it is someone who matters, I generally dismiss them by cutting them off, standing my ground, and shutting down the conversation. If I'm really pissed, I might punch a hole in the wall, or break something.
