Question on half brother/sister
My oldest sister was over my house for the week. We got to discussing family. She believes, if a brother/sister are from the same mother but different father they are considered full brother/sister. But if they are from the same father but different mother they are considered half brother/sister. I believe the only way they are complete brother/sister is if they are from both. If they are from only one parent, regardless if it is the mother or father, they are considered half brother/sister.
What do you guys think/believe?
