"Treat your family like friends and your friends like family."
It all comes down to RESPECT. Respect is how to develop the relations you want. If you want to keep your family close allow them to see the inner you and become friends on both sides. You don't have to share EVERYTHING but opening up shows that you want them in your life and be aware of the everyday that goes on. What happens and it does that your friend is not happy that uncomfortable conversation and look of surprise when you either drop a bomb or great news doesn't hurt them because they didn't know.
My friends are my family only those are close. To have my friends as family comes down again to RESPECT. No one has to be like but the person needs to be respected as a individual.
