I'm very confused by it. For two reasons,
One, I hadn't heard about it before now, I never read the book but it's been out for a while no? Does that mean this type of thing is normal?
Because two, I don't have siblings so I don't know how that works as far as ..... experimenting.
I'm actually surprised to see no Jezebel anything about it, maybe out of respect to Lena (LOL?), but.... what are some of your thoughts?
ETA the article I read on it from Buzzfeed
