I do seem to remember a process where you people ask me questions and I give you answers, and then I ask you questions and you give me answers, and that’s the way we find out things. I think I read that in a manual somewhere. — 2010

There has to be a dialogue, and it has to be a two-way conversation.  If the other side is refusing to talk to you, you are wasting your breath.  If all you’re doing is talking at them, you’re doing the same thing.  If you’re both blasting the other with rhetoric, histrionics, or just plain anger, then both of you need to go to a neutral corner for a while.
