LOL!!!! Well then again, the old saas is a lot more cultured, mature, calm, and quiet...as opposed to the new saas, who likes to think that she's cultured (remember the lecture she gave to Anandi during the Sankranti fiasco)..but if she was all that cultured, then she wouldn't have made a national announcement about her son's married life!
This new saas is modern..and being modern sounds all hunky dory when it comes to equality in the household, accepting a divorcee with open arms, etc...but when it comes to more deep rooted issues like the one being shown in the show...these modern sasumaas are the worst!!! I mean, I haven't seen much of Sumitra (I've only watched everything after the 1000th episode)..so I can't be too sure of this..but from whatever little I have understood of her character, she would never, ever interere like this in her laado's life..or even in Jagya's life if it ever came to that...she would keep mum due to sharam.
So, I guess essentially, it boils down to the differences between a sharmeeli saas and a maha-besharam saas! ;P
