I am convinced Lisa and Karly are siamese twins they are ALWAYS together?

Cant they spend one hour of the day talking to someone else instead of bi*chng and moaning all day long!
None of the other housemates can talk to one of them without the other right on her hip!
If Karly is evicted Friday

it will be really interesting to see how Lisa reacts without her sidekick and see if dogface and charlie form relationships with the other housemates?
