Can you blame them? The second Wolfy showed any confidence, she was booted out the front door.
...which I still find silly, by the way. A little confidence never killed anyone. It's better than being full of self doubt and pity. That would only make your time in the house even worse. If you applied for the show in the first place you must have had a belief in yourself that you could win. No point in being paranoid all the time, hope for the best then enjoy each day as it comes!
