Apart from the obvious ^^^^^.....I think it helps pass the time having a siesta, must be boring in there without any mental stimulation whatsoever

BB have just played the alarm to get Caoimhe out of bed. They stay up half the night, then fall asleep during the day.
I think Corin may have a point about her.  She  went to the clean and tidy kitchen, drank a glass of water and left the dirty glass on the worktop - no doubt for someone else to wash up.

And speaking of bedtimes.
Caoimhe, Shabby and Ife was, as usual very late last night.
Cigarette, bitching and teeth cleaning. Then start again. Then all over again. On and on.
But Ife was called to the DRoom and she was asked to change all the batteries in the housemate's microphones. The 3 of them did this, inevitably disturbing the sleepers.
Then within the hour BB asked them to change the batteries again!!!
Now it cannot be urgent to change batteries when the users are fast asleep.
So do you think this was done to persuade the 3 women to go to bed (which they did after the 2nd battery change) or even to disturb the sleepers?
After the 2nd battery change, they quickly decided not to do any further smoking, teeth cleaning and bitching.
