Never Let Me Go-6-Flashback

"But what you must understand is that for you, all of you, it's much, much worse to smoke than it ever was for me." (pg. 68)
The entire book has been told in flashbacks, which was fine, but now I'm starting to get frustrated by it. Kathy knows everything. She knows how this turns out, and she knows the answers to all the speculation going on. It's not like most books where we're waiting for the protagonist to figure it out. She needs to just come out and say whatever this big secret is. From the end of this quote to the page break on pg. 69, Kathy's even more cryptic about whatever it is that makes her and the other kids so special. She hints at it, but she doesn't say anything new. There are so many little stories and occurrences, and they don't seem to go together at all. Kathy is just spending a lot of time telling seemingly meaningless stories, and I'm ready for there to be some direction to what she's telling us. I thought the incident with Madame a few chapters ago would kick it off, but nothing major has happened since then. There have been the hints and little teases, but that's it. It's really frustrating, and I'm ready for Kathy to quit dragging the secret out.
