Quote 22
Brazil was beastly but Buenos Aires the best. Not Tiffany's, but almost (19.1).
Holly's postcard tells us that she has secured her literal freedom in that she has escaped the authorities and is living her life in South America. But she still hasn't found her Tiffany's quite yet.
Quote 23
Holly suggested she run out to Woolworth's and steal some balloons; she did: and they turned the tree into a fairly good show (8.4).
We're not condoning stealing here, but in some ways the act of stealing represents freedom for Holly. She doesn't have to steal, but she still does because she can. She's just exercising her right to do what she wants, legal or not.
Quote 24
Even so, whenever I felt in my pocket the key to this apartment; with all its gloom, it still was a place of my own, the first, and my books were there, and jars of pencils to sharpen, everything I needed, so I felt, to become the writer I wanted to be (1.1).
Even though his apartment is small, old, and dingy the narrator loves it because it's his. This apartment is home to him because it represents the start of his career as a writer and the beginning of life on his own.
