Wud like to be Archana if she is educated... yes, that's perfect... an educated Archana is wat I'd love to be. Then she wudn't be so meek. Cos i think that's where the most basic difference btw the two sisters lies. Since Archana's hardly stepped out of the house and led a very sheltered life, she's underconfident and meek, for her, her only world is her family, so she's ready to do anything for them. Varsha having studied and worked outside has become resistant to the big bad world, and so doesn't take things lying down.
What Archana has and varsha doesn't however is maturity and wisdom, I mean, when she came to Manav's home she handled all the issues and tiffs so well and with such maturity that if Varsha had been in her place she wud hv fought on the first day and there wud hv been big problems on the first day.itself in the family. And in this respect I dont find Archana's character unrealistic at all, cos even my mom had very similar problems when she got married with only my dad supporting her(that too in an arranged marriage) but she handled things in a similar way and all was peaceful.
