Exchange Theory
Grace, you are right when you say that as we become an adult, the way we define family changes. For me as a child, I thought family meant only people who shared my blood. However, as I became an adult, I have friends that became my family. As for the exchange theory, I feel that it is the reality that exist in our society now. People who are married or cohabiting are with each other because it benefits them. If this was not the case, than we would not have people breaking up or divorcing. Everyone has to be getting what they need in order for the family to stay intact.
