Quote #10
"It's really hard, snipping things out of time: you have to make sure that the edges all line up, and even Gran doesn't always get it right. And this would be harder than that. It's a real thing. I don't think even Gran could take it out of you without hurting your heart. And you need your heart." (14.14)
Obviously, when you mess with the sequence of time you are doing something really difficult and persnickety—and of course the edges need to line up perfectly, or else the people will have that odd sense of something not being quite right.
