One dollar and eighty-seven cents. That was all. Every day, when she went to the shops, she spent very little money. She bought the cheapest meat, the cheapest vegetables. And when she was tired, she still walked round and round the shops to find the cheapest food. She saved every cent possible.Delia counted the money again. There was no mistake. One dollar and eighty-seven cents. That was all. And the next day was Christmas.She couldn’t do anything about it. She could only sit down and cry. So she sat there, in the poor little room, and she cried.Delia lived in this poor little room, in New York, with her husband, James Dillingham Young. They also had a bedroom, and a kitchen and a bathroom – all poor little rooms. James Dillingham Young was lucky, because he had a job, but it was not a good job. These rooms took most of his money. Delia tried to find work, but times were bad, and there was no work for her. But when Mr James Dillingham Young came home to his rooms, Mrs James Dillingham Young called him ‘Jim’ and put her arms round him. And that was good.
