In chapter 23, why do you think Primrose wants all the windows in her room painted? Does she not want to see out or does she not want people to see in? Is
this a metaphor for what she might be feeling inside?

its definitely second person : )

explanation:

  this riddles' answer is library.

  the "leaves" are a reference to the books' pages that the library contains; the branches are a network of libraries that connect multiple libraries' collections, resources, and items in a system of a common database, integrating them; the branches' organization are a useful management tool for coordinating the multiple collections many libraries have.
