I'll avoid them if at all possible. If that's not possible, and they actually get ugly to me to my face (which fortunately hasn't happened in a looooong time), I do my best to remain at least outwardly calm and let the other person make a complete fool out of themselves - this usually works, as they can often take just enough rope to hang themselves. Especially in public. In fact, it's probably best to confront me like that in public - in private I might not be so restrained.
I try to remember that when someone is behaving in an over-the-top aggressive way toward me, it's not about me, it's about THEM. And what scares me most about such people is, if they'll do this sort of thing in PUBLIC, imagine what they're like behind closed doors!?
When I see crazy coming, I try to cross the street.
People are frustrating, but in my experience there's very little to be gained by shouting or name-calling back at them. It doesn't teach them anything, doesn't help their behavior, doesn't make them sorry - they're obviously damaged people if they're adults and still acting like that. Blowing up back at them might make me feel better for about a minute, but I'm not proud of myself - I feel like I failed because I couldn't figure out another way to handle it. I guess I'm more Picard than Kirk, in this regard.
In "The Art of War," it says that if you must fight a battle, you have already lost (in a sense) because you were not skillful enough to avoid the battle in the first place.
have codependent relationships. Sometimes, I can't even tell the difference between the dynamics of the two.
