Part of communication comes down to how well we "read" the people with whom we communicate. In order to communicate well, we must know how they interact with us. We have to know when people are telling us (in not so many words) to stop talking. We have to know when people are closed to us; that they refuse to relate to us. We also have to know when they are opening up. That is one sign we should not miss. Because God made to interact intelligently.
