This is pathetic social conditioning only. I've seen my grandmother eating last. She eats only after even the servants have been fed! She treats even servants and driver like her own sons/daughters! She would not even use proper soap and took bath with whatever soap that was available, even Wheel!
I've seen even how my parents don't eat properly or eat even stale food thinking it would be better to finish it instead of wasting or throwing it away!
I agree it is conditioning only. Such people will even ruin their own health but still put others above them. My grandmother is so worried about housework that even at this age, she prefers to handle it all by herself instead of just giving instructions to servant! She had an accident once. She was bedridden for 6 months. But she started getting up and doing work in kitchen, risking her own health, much to others' dismay by the 4th month itself! She again fell more seriously ill and took rest only when doctors warned her that she would never be able to sit or walk again if she did not take rest now.
I think CVs should take up this issue too. There is nothing wrong in thinking for yourself or taking a decision for your own self.
I did say I was sad to see her thinking of others. But it's not that I blame her for it.
I've seen older episodes of this serial and seen how she was rebuked and mocked by her parents and DS if she thought of herself and asked for even little things like equal share in laddoos!
Such people think it is their duty to be patient and tolerant and do things for others. They always have one argument - Apne baare mein kya sochna hai? Soch kar kya karna hai? God will take care of everything!
They are told that God will reward them for their selflessness and dedication and if someone does something wrong to them, God will someday see to it that justice is done even if it happens in the next life!
Anandi's attitude is reinforced by DS appreciating her or Sumitra and Gehna expressing awe at her patience. She gets positive reinforcement in form of good wishes and blessings.
She needs a bigger jolt, betrayal or complete change of environment, time alone for self introspection so that she can really ruminate on things and think for herself a bit. Otherwise nothing changes such men and women.
[I've seen many men also, not eating much or not shopping for themselves and letting only their kids and wives spend on things they want. They feel it is their duty to feed the family and fulfill all their desires and wants.]
