The children that are at this private school are very secluded from the rest of the world. Since they are not interactive with the rest of the world i think teaching sex very casually doesn't really effect them or bother them. I think it was kind of like since they know that they cant have children then its no big deal to just tell them everything and anything about sex. Me and my roommate have talked about this reading a lot and we both agreed at first that maybe these kids have some kinda of disease or cancer and that is why they aren't allowed to interact with the outside world. And maybe that is why madam was so afraid of them. But now that you see that they are just there to give their organs and having children isnt an option for them i believe they are clones.
I really enjoy this reading i love how it keeps us guess on where they are and why they are there and everything else about it.
