How does Muriel Barbery use imagery in The Elegance of the Hedgehog?

Imagery:

"Because I am rarely friendly—though always polite—I am not liked, but tolerated nonetheless; I correspond so very well to what social prejudice has collective construed to be a typical French concierge that I am one of the multiple cogs that make the great universal illusion turn, the illusion according to which life has a meaning that can be easily deciphered." (Chapter 2, p. 9).

"Life becomes a quiet stroll—whereas our life, in the homes we have, seems like nothing so much as a long series of intrusions." (Chapter 4, p. 139).

"Maybe I am the symptom of the family contradiction, and so I'm the one who has to disappear, if the family is to prosper." (Profound Thought No.14, p. 244).
