In this exchange, David is, in effect, assessing for competence. He has heard Christie describe exchanges with her estranged husband, John, and now seeks to enlarge the account of these, with a focus not on problems, but on competencies that she has been able to display in difficult circumstances. Notice this exchange features not a language of 'effects' but instead one of responses - while on first view one might conclude Christie 'doesn't do anything' in response to John's abusive behaviour, a closer inspection reveals that she actively responds in a highly constructive manner. David asks highly specific questions to get a picture of the choices Christie made in the face of challenges.
