Quote 19
I realised, of course, that other people used these roads; but that night, it seemed to me these dark byways of the country existed just for the likes of us, while the big glittering motorways with their huge signs and super cafés were for everyone else. (22.86)
Check out how Kathy sets up a contrast here between "other people" and "the likes of us." It's as if she's segregated the roads for different types of people. Well, this kind of thinking makes one thing clear: Kathy sure does see herself as different from the rest of society.
Quote 20
When I think about my essay today, what I do is go over it in some detail: I may think of a completely new approach I could have taken, or about different writers and books I could have focused on. […] It's at that sort of level—daydream stuff. (10.3)
Let's be honest: sometimes rewriting essays isn't that much fun. But here Kathy revels in the fantasies of how she could re-craft her work. She realizes this isn't really going to happen, but she likes daydreaming about the possibilities all the same. What do you think about the fact that Kathy likes to daydream about the past more than the future?
Quote 21
One big idea behind finding your model was that when you did, you'd glimpse your future. Now I don't mean anyone really thought that if your model turned out to be, say, a guy working at a railway station, that's what you'd end up doing too. We all realised it wasn't that simple. (12.12)
Kathy and her friends know that they aren't going down the same paths as their clone models. In the real world, their models have various jobs. In the clone world, there are only two jobs: carer and donor. So how could they "glimpse" into their future if they find their model? Wouldn't that future be incorrect?
