I recently started a work that, im my opnion, is worthy of being of novel length, but I am having a hard time making it long enough. The plot is complex enough, and there are plenty of setbacks for the hero to overcome. In most of the works I have read, the plot is developed, and the backstory revealed through dialogue with other characters, in essence. "showing", not "telling". This, I would assume, would make the read much more interesting, and more extensive. My problem is that this character is single with no siblings or children, and was abandoned by his parents. He has lost his job as well, and the depression and loneliness associated with those misfortunes play a major part in the plot, or I would have omitted them. Here is my question: How can I "show, not tell", when my hero has nobody to talk to. P.S. I assume my work would benefit from a FOIL character, and that will also be hard to achieve. All help is appreciated.
