Is the red couch magic? Does it entice bitching?
 

BB13 and this CBB has had a lot of bitching, and the couch seems to be at the centre of most of those bitch fest. Is there something about the cushions that makes it impossible for housemates to have a quiet or otherwise friendly sit down?

oops forgot the poll

The colour red is supposed to induce bad temper and fights so maybe you are on to something.
