How we cite our quotes: (Chapter.Paragraph)
Quote #4
I thought about how my grandfather's family had been taken from him, and how because of that my dad grew up feeling like he didn't have a dad, and now I had acute stress and nightmares and was sitting all alone in a falling-down house and crying hot, stupid tears all over my shirt. (5.20)
Seems like this feeling of being alone runs in the family, and it's reached a critical mass in Jacob as he thinks about how his grandfather was alone, and his father felt alone, and he feels alone. That would be hard to deal with even if he wasn't in the middle of a creepy falling-apart house.
Quote #5
There never was any girl. I'd imagined her, and the rest of them, too. (5.72)
Jacob sometimes thinks his isolation is driving him crazy enough to see things. At first, that's a more rational explanation than the fact that some kids might be invisible or able to shoot fire from their hands.
Quote #6
"We were always so desperate for news of Abe. I asked him once if he should like to worry me to death, the way he insisted on living in the open like that." (6.64)
One drawback to being stuck in the time loop is that it's difficult to communicate with the outside world. Even if Grandpa did want to communicate with them, it would be hard to get news to them.
