I recently read a book called Mindful Communication that uses a red/yellow/green light model for understanding the state of mind of the other person. In a discussion, there's a relationship; relationships are not fact-based, or in a vacuum. You have to take the immediate context as an input as well, to understand how receptive the other person is.

Or not. However, if the concern is to state facts, then it's not really a communication because it ignores the reception and betrays the actual intention of the fact-stater.
