The word or idea of "family" is so universal and accepted it would almost seem that any discussion on it would have to be personal. I believe the idea of family, however, is quite a bit more complicated (or at least should be) than what it may seem.
Family is essentially just the blood connection between people, so it is basically the sharing of genetic material. Why is it then that we have such a large emotional connection to family? (Or at least the majority of people have or are expected to.)
