You're an idiot.

"'Of course not, stupid'" (Never Let Me Go, 243).

Shortest quote yet, woohoo! This part reminded me of another part in the book that reminded me of something I couldn't remember (page 170):

"'It's not going to be in Woolworth's now, you idiot!'"

"'Tommy, you idiot.'"

"'All right. You're a complete idiot, but all right.'"

Obviously, a common theme in the relationship between Kathy and Tommy is Kathy's persistence that Tommy's an idiot. It's kind of cute! Actually, I don't think it's kind of cute -- I think I'm supposed to think it's cute.

As I said, the excerpt from page 170 reminded me of something that I couldn't remember, and when I came across Kathy's calling Tommy stupid a second time, I just had to pursue it. I talked with a reliable source, and got this information:

"Robin [from How I Met Your Mother] says 'You're an idiot,' instead of 'I love you,' and if she DOES say 'I love you,' Ted says it means she's already broken up with you in her mind" (reliable source).

So I think the conclusion we can draw here is that Kathy and Robin have a lot in common. Hey, this is my first How I Met Your Mother reference!
