...customizing the experience...

Beck: My sister just joined facebook. What do I do? She's going to see... everything.
Me: Don't add her?
Beck: No, I can't do that. She's my sister.
Me: Talk to her first, then don't add her?
Beck: What would I say?
Me: Say "I love you, but my private space is my private space... in public... on the internet... for all the world to see".
