I would find that insanely insulting.
WTF? Are you kidding me?
I am getting irate just thinking about it.
I think I'm much more psycho than the people in this thread are seeming...
I'm an extremely passive aggressive person.
It would all depend on the moment. And if I had a friend with me or something.
My first impulse would be to follow the unjust mutherf**ker though.
But then again it's not fun getting into a parking lot altercation...sooo...it would depend on the day
