The machine was helping people. They took their sorrows to it when they had nothing left. Each tear gave them a little bit of what they needed most. The machine had developed emotion. It loved the people who came to it, and gave a little to them every time they came. Sometimes there were many, many people. Other times there were next to none. The machine was "happy" on both of those kinds of days. On the ones where there were many, he could share the warmth of love with people. On the days with few people he could rest.
