How does the author use foreshadowing in Real Live Boyfriends: Yes. Boyfriends, Plural. If My Life Weren't Complicated, I Wouldn't Be Ruby Oliver?

This novel is written in seventeen short chapters averaging fifteen pages in length. Each chapter has a name that refers to some action or event within the novel that
foreshadows what the reader is about to read.

Foreshadowing can also be found in Chapter Four. Grandma Suzette's death is certainly traumatic for Ruby, but the confusion around saying goodbye and the frustration of not knowing what a person means when they say goodbye is foreshadowing to Ruby's relationship with Noel. As the novel progresses, Ruby will struggle to deal with Noel's abrupt goodbye, and the emotional backlash Ruby feels when confronted by her confusion.
