Never Let Me Go 10

"The point about Chrissie--and this applied to a lot of the veterans--was that for all her slightly patronising manner towards us when we'd first arrived, she was awestruck about our being from Hailsham." pg. 145

This motif that the Hailsham students are "special" must have a deeper meaning than I thought. Originally, I knew that Hailsham was a special place, but didn't know why. Later I learned that these students were created to donate their vital organs. That's why they were special. So, as I kept reading, I assumed that all people raised to donate their organs, like the rest of the people at the Cottages, were special too. But, according to the quote above, it seems that Hailsham in particular is more prestigious and special than any of the other places, if there are other places. I wonder why that is. Could it be that the Hailsham students are clones of more powerful and influential people? Or is it just the luck of the draw where the clones are raised? I am really curious as to why Hailsham is so highly regarded, and why they would be any more special than the rest of the clones. What is so different about Hailsham?
