Jennifer E. Smith said this quote

But she knew it would never happen. She had no intention of visiting him there. Even if she were open to the idea, as Mom and Dad both hoped she would be, the mathematics of it seemed utterly impossible to her. What was she supposed to do, spend Christmas there and Easter here? See her dad every other holiday and one week during the summer, just enough to glimpse his new life in fragments, tiny slivers of a world she had no part in? And all the while missing out on those moments of her mom’s life—her mom, who’d done nothing to deserve to spend Christmas alone?That, it seemed to Hadley, was no way to live. Perhaps if there were more time, or if time were more malleable; if she could be both places at once, live parallel lives; or, simpler yet, if Dad would just come home. Because as far as she was concerned, there was no in-between: She wanted all or nothing, illogically, irrationally, even though something inside of her knew that nothing would be too hard, and all was impossible.
