No matter whether you are negotiating for a bullock, a property, a car, a golf club, a pup or a divorce or personal injury claim, everyone has a number at which a deal will be struck and a case settled.
It may appear to be tremendously prosaic or matter of fact or materialistic to have this view.
But I believe it is true in the vast majority of cases. The rare exceptional case may have something else going on, such as status.
But, by and large, everyone has a number.
