Saroj Vyas
Treat your bahu like a daughter and not as a daughter-in-law. Na Bole Tum Na Maine Kuch Kaha beautifully conveyed this message by showing how Saroj Vyas matured.
Intially Saroj was not so keen of her widowed bahu getting re-married, but with time, she seemed to have realised and have transformed from having a traditional mindset to a liberal frame of mind.
