I think its better to say she is faking it than saying her kabhi dayan kabhi 8 sal ki bachchi projection as real. TM may be right that she is like that only. Dayan with outside people who she feels there is nothing to get anything from or her competitors and choti bachi with her family, friends and people who can benefit her. Friends and family she will defend and stand up for while wanting all their attention and the second is use and throw.
Its up to an outsider like us who is in neither of these categories to decide whether they like such characters. Some see the child aspects which she shows when with Salman and Shukla and let that overshadow her meanness while some others see how she behaves with people 'against' her family in BB and turns on her dumb act in front of Salman which is the biggest jarring note in her act because either shes a fake or Salman is in her desperate to include in 'use and throw' category.
On another note this Sidnaz nonsense was not her creation but BB's. I feel she is trying to discourage it as much as she can without harming her friendship.
