I'm working on a short story (no more than 25 pages), and it revolves around specific character traits of my 4 main characters. To really show these characters for what they really are, I'm introducing each one in a scene that doesn't necessarily push the plot forward. In some regards these scenes are trivial, but in others they are essential simply because I am using them to show my characters. Is this a good way of doing things? I can't help but feel like a reader would say "what's the point of everything that happened in this scene?" For instance, I need the audience to know very quickly, within the span of a page or two, that one of my characters is very powerful and manipulative, so I wrote a dinner party scene that introduces him and puts him in that capacity. Characterization aside, the dinner party scene has no relevance to the plot whatsoever. Is this a good way of fleshing out characters?
