Sometimes couples don't speak to each other after a fight. This not only happens to husbands and wives, but to brothers and sisters as well. We fight over trivialities, unaware that we are losing more important things in the process. The burglar in this story represents Satan, who comes to rob us of our peace, our happiness and our ideals. He is successful when we don't have deep communication with one another.
People expect the other side to apologize first after a fight.
Or they speak to each other just to keep up appearances, but not from the heart. We call ourselves brothers and sisters, but we often don't speak to each other. We may speak externally, but not from our hearts. If we continue like this, we'll lose everything just as the old couple in the story did. They couldn't put themselves in the other's position, but thought of themselves as separate individuals.
