watching you go the bathroom. It's super weird. Especially the first three days. My roommate, Scott Junk, and I would be talking at night and they would just bust in the room. There is four different settings of light and they would blast the highest setting and start filming us. We'd be like, 'Come on, man. It's two in the morning.' And they're not supposed to talk to us, but they'd be like, 'Stop talking and we won't come in here. If you want to go to sleep, go to sleep.' If you started talking at all, there's people camped out, ready to come in. That, I really had to get used to. It was a big change. The camera men are 'supposed' to be ghosts. We are told to pretend they aren't there. It's kind of hard whenever there is a camera in your face or a boom mic in your face. After three days though, you're able to have the conversations you want to have and you don't even hold anything back in front of the cameras.
