"The designer has an obligation to provide an appropriate conceptual model for the way that the device works. It doesn't have to completely accurate but it has to be sufficiently accurate that it will help in both the learning of the operation and also dealing with novel situations."

So, as you can readily see from what I have said thus far, a creative, active, sensitive, accurate, empathic, nonjudgmental listening is for me terribly important in a relationship. It is important for me to provide it; it has been extremely important, especially at certain times in my life, to receive it. I feel that I have grown within myself when I have provided it; I am very sure that I have grown and been released and enhanced when I have received this kind of listening.
