Family Quotes in My Sister's Keeper

How we cite our quotes: (Part.Chapter.Paragraph)

Quote #7

"No offense, but you don't exactly look like a parent." […]

"What do parents look like?" (3.6.108-3.6.109)

Good question. We think the answer in this case, at least with Campbell, is that parents are supposed to look responsible—and this guy barely looks like he's capable of carrying groceries (based on the fact that his fridge only has ketchup in it).

Quote #8

One Thanksgiving when Kate was not in the hospital, we actually pretended to be a regular family. (3.7.71)

Is there such a thing as a regular family? We think most families have to deal with things like illness, badly behaving teenagers, and other mistakes and maladies. So maybe by ignoring all these problems, they're pretending to be an abnormal family.

Quote #9

If you have a sister and she dies, do you stop saying you have one? Or are you always a sister, even when the other half of the equation is gone? (3.7.85)

Can you answer this one, math majors? Are you the variable formerly known as sister, or do you change to a different type of integer altogether?
