I was watching the live feed on E4 around 11.30 p.m. last night, and the housemates were practicing their bell-ringing task.
After a few false starts, they actually succeeded in getting right through to the end of the 'tune' without a single mistake!!
So there IS light at the end of the tunnel. I hope they do pass this task - they've all worked really hard on it (even Fed!!!) and they deserve a bit of reward. Well, I think so anyway.
