How does Carolina Maria de Jesus use imagery in Child of the Dark?

Examples of Imagery:

"I classify Sao Paulo this way: The Governor's Palace is the living room. The Mayor's office is the dining room and the city is the garden. And the favela is the backyard where they throw the garbage."

"Oh Sao Paulo! A queen that vainly shows her skyscrapers that are her crown of gold. All dressed up in velvet and silk but with cheap stockings underneath - the favela."

"July 15: Today is the birthday of my daughter Vera Eunice. I can't give her a party for this would be just like trying to grab ahold of the sun with my hands."
