Hi guys!
I think Nanu is not held accountable for how Meenakshi has turned out. Despite all his big talk, he is nothing but a mute spectator to Meenakshi's shenanigans. He is also blinded by love for his daughter because he is usually the one who bats for her when Abir has given up on her, like before MishBir's wedding.
I feel that his lack of strictness with Meenu has turned her into the monster she is. She has a raging ego, has no conscience and believes everyone is a pawn to achieve whatever it is she has set her mind to. Despite this, Nanu keeps parroting the line that 'Meenu jo bhi karti hai sabke bhale ke liye karti hai'. How about NO?!
When a person feels their actions have no consequences, they start losing their sense of right and wrong. At least all the other characters have people who rein them in, Meenakshi doesn't. Abir doesn't count here because Meenakshi sees him as her dheet beta. Only when she is told that she is wrong by someone like Nanu will she change.
My reaction when Nanu starts giving gyaan-
He is really a useless parent. Meenu has taken over and he has no qualms in inflicting her on his family and now another family.
What say?
