As far as Nikunj is concerned she does have her piercing way of talking....(sorry if I am being somewhat racist....but I feel this is kind of characteristic of Haryaana Jaat ladies... she is still more sophisticated than the other Haryaanvi Jaats coz of education...but then people stay tied to the roots to some extent)... Not just Nikunj, but till now I have felt a vibe of arrogance from so many Haryaanvi Jaat ladies...that I feel its so much cultural .... I dont know if any of you have watched "Na Aana Is Des Laado"..the 'ammaji' serial..I have seen 2-3 episodes...but it just depicts their culture really. Nikunj doesnt have that Haryanvi accent....but does have that offensive attitude to an extent.
Apart from this somewhat offensive communication, she seems responsible and diligent. And everyone has some drawbacks or the other....and some cultural background too...but no one is black or white..we all are shades of grey..and its just mature to remember that before being too judgmental.
