A good plot is crucial to a good story. One of the oldest and most widely used plot devices is the love triangle. Two guys chase one girl, or two girls chase one guy. Same old same old.
But, why stop there? We should extend this to geometries of all sorts. Imagine the complex web left after a child has unrestricted access to a can of silly string. It would be a story so full of short-term relationships it would resemble middle school dating habits.
A love story of that scale makes love triangles seem like children’s stories.
