What does family mean to you?

Family is such a central and important thing to this world. It is something that Heavenly Father created so that we can have an essential part of life. Without families we are nothing. So, what is family? To me family mean a unit that will always be there. Family is consists of loving parents and siblings. Like, The Family: A Proclamation to the World, the family should consist of a mother and a father. I don't think that same sex marriage and "parents" are something that intended. Nature is meant for husband and wife. Your thoughts?
