Sometimes we are asked to respond to what other people say, or to produce ideas in response to events, without having a particular problem that needs to be formulated and solved. There are more or less creative ways to pursue these less focused mental tasks. In talking to a friend I can use trite phrases or I can try to say things in a fresh, topical way that more closely represents what I feel at the moment. I can use stock images or try for more vivid ones, based on common experiences.
