The Look

There's a look that comes over men's faces in this part of the world when a woman starts trying to make a point beyond any mere statement about the weather or what is being served for lunch. When I see that look come over a male colleague's face, I know that I am no longer being heard. I may in fact be sitting there speaking Chinese at that moment. And at the point, I have to clearly resist the desire to give the guy a good shake. Even more annoying is when that look comes over the man's face, and then he begins speaking, interrupting me in the middle of the dialogue, and he usually repeats the same point that he was making before I started speaking.

To be fair, it is a phenomenon that sometimes happens with women, but much less often.

The odd thing is, I don't know how to respond other than to basically speak over the man and keep asking him to let me speak, repeating myself until he complies to my request.
This type of conversation usually begins when we don't agree on how to proceed with some task at hand - the latest case was a survey. For me, a conversation is about each of us expressing our point of view and then coming to a consensus on how to proceed. But for the man, its as if its a conversation for everybody to agree with him, thus the reason he turns off his ear drums and just keeps repeating himself?

The most frustrating thing for me is the waste of time it takes to go through the process of getting the man to a point that he will actually 1) listen and 2) understand what I have said. I repeat myself, he repeats himself, I repeat myself, I am interrupted, I wait for him to finish, I try to re-phrase what I've said, I am interrupted, I then interrupt him, and on and on. Is there a better way to do this?
