There's A Hard Life For Every Silver Spoon

Look at this definition of family:

any group of persons closely related by blood, as parents, children, uncles, aunts, and cousins: to marry into a socially prominent family.

This is the 4th definition for family at Dictionary.com
Of course, I'm using this definition just to defend my little story.. no not story... just something to think about. Some people say a family is only a family if biologically related. Well, listen... and think... to/about this:

Imagine a mother, father, and daughter. A typical family. The mother dies. The father remarries to a woman who has a son. The marriage doesn't work out, and the mother leaves. The father dies. The two children are taken under the guidance of a legal guardian. Their guardian decides to adopt from a foreign country. Then, the daughter's best friend moves in with her because her family has too many issues. So now you have the daughter, her best friend, her step-brother, the legal guardian, and the adopted child. Five different blood lines, five people who aren't at all biologically related. But they are a family.

See? Nice, right?
