What do we learn about Jim and Della in the first five paragraphs of "The Gift of the Magi" by O. Henry?

The married couple Della and Jim live meagerly with few possessions in a furnished apartment. Jim makes $20 a week at a job where he used to make $30. When Jim was making $30 a week, the couple placed a name card on their mailbox which read "Mr. James Dillingham Young." Now that he makes less, the middle name Dillingham looks blurred (in an example of personification, the letters themselves are contemplating contracting to a simple D. because of Jim's pay cut). With Christmas approaching, Della is trying to save money for a gift, but has accumulated only one dollar and eighty-seven cents. Sixty cents of this money has been garnered through "close dealing" with the grocer, vegetable man, and butcher. This bargaining causes Della's cheeks to burn over the idea that she has to be so stingy with her money. She counts the money three times and finally breaks down and cries on her "shabby little couch."
