xyz in many houses once a daughter gets married and daughter in law comes. If daughter try to do something that is called interferenc. saat phere is just story. But in real life Bhabhis won't allow it saying this is not your house anymore. They will even make you feel like you are the guest in your own house. Also I am against the law that gives the right to son in laws that can inherit father in laws property. We will have more people like dheer who will marry for girls parents inheritance.
I agree parents can stay with daughters and sons. I believe daughters will take care of parents better than sons.
I agree with you especially with this "I believe daughters will take care of parents better than sons". Exceptions are there but in general I too have seen that! Thank God my bhabhi does not make me feel like a gues at my parents but hey she does not live with my parents either. My parents even now say that if my brother were to stay in the same town as my parents they would see to it that they stay in a separate house independently. Works well for everyone.
