What is Family?

What is family?
Is it just people related by blood or marriage?
What about a man, woman, and children in a household?

What about a single parent and children in a household?

What about a blended household?
What about a man and woman aren't married to each other?
What about two women or two men raising children?
What about grandparents raising grandchildren?
What about foster children in a household?
What about blood relatives who are estranged?
What about a circle of friends?
What about internet contacts?
What about the people in your club?
Is it just people of the same race?
Is it just people of the same nationality?
Is it just people of the same religion?
Or is it bigger than that?
Aren't we all members of the Human Family?
Why can't we act like it?
