So when a daughter marries they just ship her off

To her in laws and forget her?

May be kamini killed her or send her to mental asylum.. Oberoi forget that they have a sis/daughter..

To this topic I would say it is very easy for parents to forget their daughters. In real life as well. It has been just three months since Ranveer and Praanca got married. Itney din to bas hi hallo se kaam chala letey hain larki ke ghar waale. aage poochne ki zarrooorat bhi nahi samajhtey. this is very common and normal in Indian context this is the only logical thing ever shown in Indian shows. Not that there are no exceptions in real life to all this but they are still few.
