coming to the bahu list
I feel Sadhna Ragini top the list. I think they sometimes feel for the MIL more than even the sons. Where Ragini is always trying to make Ranveer understand not to leave the house, Sadhna is hell bent on making Alekh understand that a mother's love can never be suspected. All four want to stay together in a joint family, even they want to include people like Naveen, Avni, because they know family is only complete with all.
On the contrary look at Malti how she is hell bent to break the sharma family and wants a house for her own, where she will not allow anyone.
Next comes Avni, someone can help me describing her.
It all depends on sanskars and what you learn while one grows up. We are all taught to share, even Malti and Avni also must have been taught, but when it comes to execution, they have only one concept, stay separate and dont allow husband to feed even the old parents, or take care of a needy brother or sister.
