My aunt who was so into education and then work quit to have a family life now actually struggles to cook and feeds her daughter junk food because it convenient.
Where as Sandhya is concerned ok so she didn't learn in from her parents, but atleast she is willing to learn and she wants to learn. Bhabo should atleast appreciate this and it gives bhabo the chance to train Sandhya the way she wants the household chores to be done and Sandhya not being able to compare how she done them at her parents home.
I have one aunt who never learned household chores and refused to learn when she got married and now she struggles and another aunt who knows how to do it but is too lazy and thinks she knows everything. Bhabo is lucky with Sandhya she can mould her
