The meaning of family

The meaning of family is something i think all people think about constantly. I have called people who are not blood related to me by "brother" because I've known him for years. the the word family is just a word, people use it for everything they call there pets family, there friends, plants, characters on TV, they use the word loosely. its like the word good, good could be a feeling, a person, a place, a thing it could be bent for the situation. I think family is what ever you think it is whether its a dog or a tree it could be your family.
