How we cite our quotes: (Chapter.Paragraph)
Quote #7
I realized that, to my mother, it no longer mattered what I read. To her I was already dead. (3.200-201)
The closest David's mom can get to telling him she loves him when she thinks he's dying is replacing his copy of Lolita, which she threw out because she thought it was pornographic.
Quote #8
She had come to say goodbye and to grant me my last wish. Then, when it looked as if I would live, she had come into my room and taken the book back. (3.202-203)
David's mom was able to communicate with him—although in a very limited way—by giving him the words he loves: Nabokov's words. But when she realizes he's not dying and might actually be able to read those words, she takes that communication back.
Quote #9
A neighbor saw the smoke, saw her dancing around and phoned for help. Papa John was saved and Grandma was taken away to the state insane asylum. (4.102)
David's grandma may have burned him, but she actually set her husband on fire. Okay, her house with her husband in it, but still—same thing. If David grew up to have issues with women, we wouldn't exactly wonder where they come from.
