The one chapter I loved was the "broken record." My husband attempts to explain the same thing over and over to his ex-wife because she has a tendency to re-interpret EVERYTHING said to her and so his replies would sap time out of our lives while he rephrased it over and over and over again. Now, he cut and pastes the answers so that she will eventually get the point, or not. We are lucky that only one parent has sole decision authority because when in a circumstances where one parent is mentally or emotionally off kilter, there is no chance to communicate instead conversations become informational only.
