Meaning of Life
The story seems to revolve around how finite life itself is. Though the protagonist tries to spend her days writing her story, ultimately, she is unfulfilled by her melancholy life until R comes in. By helping R she gain a purpose to her life beyond merely existing. Moreover, the most common place of objects begins to lose meaning and fade from the protagonist’s mind. Perhaps this is a reference to the idea that we do not realize the importance or significance of a thing until it is gone.
Freedom
The memory police are portrayed as a oppressive force that are making people lose their memories. Though there are those that are immune to it, our protagonist is not so lucky to be one of them. Instead, she uses typing as a way to express how she feels. She types the story about a woman being trapped and losing her voice. This is a creative outlet for the protagonist to convey her feelings of being trapped in a oppressive system.
