ANGER IS FEAR’S BODYGUARD, a poster in the hospital had read (Chapter 9, p110) — Celeste Ng

To a parent, your child wasn't just a person: your child was a place, a kind of Narnia, a vast eternal place where the present you were living and the past you remembered and the future you longed for all at the same time. You could see it every time you looked at her: layered in her face was the baby she'd been and the child she'd become and the adult she would grow up to be, and you saw them all simultaneously, like a 3-D image. It made your head spin. It was a place you could take refuge, if you knew how to get in. And each time you left it, each time your child passed out of your sight, you feared you might never be able to return to that place again. (Chapter 9, p122)

Anything had the potential to transform, and this, to her, seemed the true meaning of art. (chapter 13 p188)

the problem with rules...was that they implied a right way and a wrong way to do things. When, in fact, most of the time they were simply ways, none of them quite wrong or quite right, and nothing to tell you for sure what side of the line you stood on. (chapter 16, p269)
