Have you ever sent an email or left an important phone message and not received a reply? What did you think it meant: Did you assume the person was brushing you off? Mad at you? Not interested in your idea? Did you spend a lot of time thinking about this and perhaps even worrying that you said something that was offensive? Or did you ever complete a project that you thought went well and didn't receive any feedback? Did that send you into a tailspin of anxiety?
