The way Kaushi's psycho nature is getting on the nerves day by day, I think Ragini is just giving her test of patience to her mother. Being a good daughter and moreover a good human being, she does not want to be rude to anyone, especially her mother. But a day will come very soon, when Kaushi has to face Ragini's wrath, because people like Ragini does not get upset soon, but if you test them and take them to the edge of their patience, the impact is going to be bad...I hope a day does not come for Kaushi, when she loses the love of her own daughter...
I think the creatives should give this impact to Ragini's character and thus can prove Ragini to be a strong character...And by the way, if someone behaves strictly with ones parents, because he/she thiks that what parent is doing is not right, then he/she has a justification. Just like parents scold us just to become better human beings, its sometimes good to speak straight even to elders, just to make them realise that they are wrong... its not we need to disrespect them, but in doing so, actually we are saving our elder not to commit any more sin...after all its for the wellbeing...
