[Nowhere]

If the housemates were to ignore Susies' sly facial expressions and opinions on people running around and generally being silly in her world, then people would look at them,as inconsiderate... I'm sure they don't want friction, and so if they were to carry on running around etc, then Susie would get irritated,thus causing an atmosphere. They want to keep the peace. Susie is so unlike any of the other housemates in there,and the majority of people viewing, so her preferances are clashing with those who want to have fun.
