"Spring in Fialta" explores the pain of missed opportunities, of "what could have been"s, and of the briefest of encounters with a woman who "had always either just arrived or was about to leave." The relationship on which the story focuses is indeed a transient one, built from a series of ephemeral meetings that are over as quickly and randomly as they began. Victor, the narrator of "Spring in Fialta," struggles to find meaning in these encounters despite their brevity. One of the story’s possible conclusions is that life is as transient as the series of moments which comprise it.
Victor only thinks he loves Nina because her ephemeral nature makes a relationship impossible. He wants what he can’t have.
"Spring in Fialta" argues that life is made up of a series of moments, just as Nina and Victor’s relationship is the composite of all their momentary encounters.
