If one thing is clear in Never Let Me Go, it's that Kathy is obsessed with the past: with Hailsham, her erstwhile friends, her old cassette tape, all of it. In fact, she's so into her past experiences that she barely tells us anything about her present life. Instead, almost the entire novel is a series of flashbacks. But why is it so important for Kathy to look back over her life? Well, for one thing, all of her old friends are gone, so they exist only in her memory. Looking backwards is one way Kathy can cope with all the things she's lost over the years.
