"I guess I have this instinct of who cares about our family... but I think it is interesting to look at this one thing that happened and how it's refracted in so many different ways."
Sarah's sister is asked what she thinks about the documentary and replies with this quote. She considers the fact that other people wouldn't want to hear about her family, remarking that it is a bit embarrassing for her. This being said, she considers it some more and concludes that the story of her family is interesting. The revelation about Diane's affair is something, according to Sarah's sister, that had a wide-reaching impact for the family.
"She was the most fun I could think of as a child, she was infectious, enthusiastic, and excited about everything."
In this passage, Sarah's sister describes her late mother, depicting her as fun-loving and exciting. This is supported by her friends and other relatives, who all comment on Diane's vitality and enthusiasm. A few relatives comment specifically on her laugh, which was apparently loud and warm. Overall, Diane was an extreme extravert and loved nothing more than being at parties or around other people.
"Michael was a private person and Diane was definitely not a private person."
Diane's vitality and extraversion can be contrasted greatly with her husband's introversion and calmness. The differences between the couple is something that is commented on by Diane's family members, with one friend even saying that they often couldn't understand how they worked, because they were so different. Ultimately, their greatest difference was the fact that Diane was an extreme extravert, while Michael was more of an introvert.
