I have used abstraction in three different ways here to express meaning. This person was sitting in an alcove in the entry hallway of a senior citizens residence. I took my vantage point from off to one side, enabling me to hide more of the person than I show here. We only see legs and feet. Using my spot meter, I exposed for the reflections on the tile floor, which causes those legs and feet to become a silhouette. And I use my frame to remove the upper half of the subject entirely, drawing attention to the body language of the abstracted legs and feet. These three levels of abstraction combine to express the essence of waiting: the passage of time.
