Most old-school desi women would never file for divorce the way Anu did (and I was impressed with her at that point), neither would they easily leave their in laws house/sasural (as Anu didn't either) but those ladies would never agree for their sautan to come and live in their house... never in a million years!
Same way they'd never allow their kids to get away with acting the way Toshu or Pankhi do... and come to think of it many would probably take the chance if their maayke wale are ready to take them in in this situation, rather than flat out reject their offer...
It's starting to become obvious that many of Anu's failings can't really be put down to how she was raised or the society she lives in, and her own personality has a lot to do with it all...
