Why Would A Family?

It's as individual as each person. What works for some, doesn't work for others, Just as some mothers go out to 'bring home the bacon' and the dads are 'Mr Mom'. To each his own. What does it matter anyway? As long as our life works for us, shouldn't we just make sure our's remains that way and let other relationships do the same? Our world would be so much less complicated if we would stay in our own backyards!
