on Helping Writers become Authors:
Stories are made of scenes.
By one of their simplest definitions, scenes are transitions.They signify a change of some sort—an arc.
They start in one place (whether a physical place or an abstract “place”), and they end in another. This is how we determine whether something happens in a scene and whether it “moves the plot.” Therefore, by definition, we can see how scenes may be viewed as essentially a whole of two halves.
