I was amazed at one of Skupin's comments, about Carter getting voted off: "He really took it personal."
Poor grammar aside, his did he expect Carter to take it? He's been out there for 30-some days trying to make it to the end, of course he would take it personally when someone ends that chance for him.
I think that people really never think about the cost of blindsides in the game. When you get control of the game and vote out your "enemies," it's expected, and they often can end up respecting you and voting for you if you make the final 2/3. When you turn on your friends and vote them out before it's completely necessary, you are making enemies on the jury far worse. Everyone talks about "bitter juries" but it's human nature to seek revenge on someone who betrayed you.
