I really think Sharda should go missing from the house. Most of the people don't understand the importance of her being home anyway. If she is not in the house, the members will realize how essential she is in every day life.
She literally helps her husband get dressed! Latika shamelessly drops of her daughter at the Modi house every single day. Dadi does nothing but criticize/taunt/speak against Sharda all the time. Chirag only cares about money. No one knows that their life DEPENDS on Sharda.
Sharda needs to prove to them that she is the pillar of the house.
