Grammar and language

We think the grammar and vocabulary of the book is simple and even though you don't understand every word  you can still figure out the meaning of the sentence/paragraph. (Well, most of the time :) )
An example of a complicated sentence "Despite her willed stomping and pitching in its street and byways, the city itself had very little to do with her interior life." You have to read this sentence a lot of times to understand what it means. It's a metaphor. She compares her feeling with New York, but her feelings have nothing to do with the city.
Because Susie is in heaven she knows how everyone on Earth feels and thinks, she comments their thoughts and feelings to the reader and also how she thinks about it. The result of that is that there's not so many long dialogues, but instead many short ones.
Example of an short dialogue: "Do you really want to honey? she asked him. Please, he said."
Susie is a teenager when she is telling this story, so the language is pretty fashioned and in a way teenagers speak (in the 70's).
