It's weird how unfazed kids are about how his mom gets offed by a hunter right at the beginning. My brothers and I wouldn't touch mushrooms, though, because what if we turned bright green and died? And then the Pet Boy tickled me by suddenly saying, "what, turn back! look, Celeste is his cousin! how can he marry his cousin!" I explained that this is France. It is France, really, isn't it? Certainly the Old Lady lives in France and I guess the elephants live in some French-owned part of Africa. Cameroon? In the end I just told him that elephants were allowed to marry their cousins and in some places (even the US) people can, too. He found the concept dismaying.
