in my family room:
Middle Sister's friend: "Hey, can I get on facebook from this computer?"
Middle Sister: "Sure."
Me: "Hey, if you're on facebook in here, you've gotta keep it friendly."
Middle Sister's friend: "What does that mean?"
Middle Sister's other friend: "That means you can't say any mean stuff."
Me: "Right, and keep it G-rated, guys."
It might be time to install that keystroke logger...
