Discussion: 'Diary of an Interesting Year' and Parents' Night

Two paragraphs please:

1) Describe the journey of the diary itself in "Diary of an Interesting Year" by Helen Simpson. What time does it span and what ultimately becomes of it?

2) There is a thing in fiction - a device used by authors - known as the unreliable narrator. This refers to a story told from the point of view of a character who may have a distorted view of the events described, or who may be spinning a version of events to present themselves a certain way. Describe some places in "Parents' Night" by Helen Schulman which indicate that the woman telling the story may be less than trustworthy.
