Possible spoilers for the book Veronika Decides to Die

One night during my time in the barracks, I finished reading Veronika Decides to Die by Paulo Coelho and realized how intertwined our life stories are, and how fragile and unstable the line between main plot and subplot in stories can be. In other words, we can never be certain whether we are the side story or the main story in the narrative we live in. Are we the protagonist or a secondary character? Is the story about us or someone else, and are we just a subplot in their story? On the surface, in any story, someone who seems to be on the periphery might actually be at the center of their own story, and vice versa.
