[Three-hundred days... that doesn't mean much to Nathan. He has only been in the dome for a fraction of them, and he doesn't really care if he leaves. He'll be trapped and crazy whether he's here or at home; all that changes the scenery and the company, and the company here beats any he would have at home.
Nathan has little interest in games and food and having fun. He's here to people-watch. The people he is watching are in no way obligated to humor him!]
