Della thinks of her husband as if he were a king. Della cares about Jim very much and she thinks of Jim by cutting her hair and selling it for $20. And with the money she received from her "hair cut" she had bought Jim a silver chain for his grandfathers golden watch. At this time he was using a leather band. Della knew that his watch was very important to him, so she bought him the silver chain. Thus fore she wouldn't be considered self- centered. Hope this helps. If you have any more question about "The Gift of the Magi" just ask me and I'll answer them. :)
