- Sean Patrick Flanery: Privacy is my most prized possession. If you're famous, you can't be an asshole. If I want to complain about the service at a restaurant, I can do it being Sean right now. If I was Brad Pitt, forget it. I'd be attacked for being pushy. Now, I can say, "Hey, you suck as a waiter," because I've been a waiter, and I know how to be a good one. You lose a lot of your rights when you're famous. I cherish my anonymity. I'm not sure what I'll have to deal with if fame hits. I can hide behind my characters, but I don't want to be dissected as me.
