It is so interesting how "kin" varies so widely throughout the world. In some societies with multiple wives to one man, the children of them will just consider all of them mothers and not worry about blood. While here in the United States, we have whole TV dramas about finding your blood related mother or father. In the U.S., we have definitely glamorized being a blood related parent more than someone who takes care of kids they have taken duty of. Even now, when speaking of adopting a child, there will still be people that say "When are you going to have real kids" or ask women why they won't have kids if they don't want them.
