Sugar and Honey is the title of the story as well as the nicknames that Douglas and Phyllis have for each other.The symbolism of the story title lies in the fact that Douglas and Phyllis call each other by those nicknames.
It really means a lot to Douglas to hear his nickname in her condition because Phyllis has always taken care of Douglas and in the story he, now,has to take care of her. It makes him feel hope that she still remembers their nicknames at least for a few minutes.
