I only flip people off after they perform potentially fatal jackassery. Of course, when I do I am often rewarded with intentional hostility and violence. People trying to hit me with their car doors, people jumping out and swinging at me, being run off the road, you know. Then I get really incensed to a point where I am afraid of what I will do to a person. It really makes me feel so horrible, all that rage and adrenaline. Lately I've been pretty chill, but then again no one has tried to intentionally kill me in response to a hand-gesture after narrowly avoiding (of course the avoiding is all on my part) accidentally (absent-mindedly) killing me. It's a ****ty situation all around. I'm practicing a more spiritual solution.
