I think Anandi has gotten over this issue of Pallu.It doesn't seem to matter to her anymore.
She covers her head when she feels like it and doesn't when she doesn't feel like covering her head.
But for Shekhar parivar it is an issue because they take pride in being * Maadarn* and consider themselves to be of progressive mind set.The testing times are for them more than Anandi.
Anandi can't help about the things that have happened in her life.It's not her fault that she was a balika vadhu and a divorcee and she was raised by the people who were supposed to be her in laws.Her decision to adopt a differently abled child is not something that is cringe worthy either.
Though the silly old lady may raise questions on these issues.
It is upto the family to answer the questions because it was their decision to accept her as a bahu.
