How we cite our quotes: (Part.Chapter.Paragraph)
Quote #4
"We all know you're supposed to love your kids equal, but that's not always how it works out." (4.1.48)
Forgiving Brian's grammar here (adverbs, people—use them), do you agree? Do you think parents play favorites? Does Brian love one of his kids more than the others? What about Sara? Do the kids realize it?
Quote #5
"The bottom line […] is that we never fall for the people we're supposed to." (4.2.84)
Love happens out of the blue, it seems. Although by the time we finish this book, it seems that Campbell is supposed to fall in love with Julia, so we guess it depends on who is doing the supposing.
Quote #6
"I had the heart of the relationship, and no body to grow it in."
"What happened then?"
"What else," I said. "It broke." (4.2.101-4.2.103)
This sounds like plot of a Picoult-meets-Frankenstein story. But what Julia seems to be saying is that she really loved Campbell, but he wasn't there to support her. She put her heart on the line, and he left it behind.
