During an argument, Pat told her boyfriend, Jim, that it bothered her that they never made plans ahead of time. She felt more comfortable and secure if she had advance notice and a better sense of their plans. Jim didn’t answer; he just changed the subject. He continued calling only at the last minute. She mentioned it again, but again he ignored her. Finally Pat gave up on the relationship. In these cases, what Rob’s girlfriend and Jim didn’t say spoke louder than any words.
