Be nice and respectful towards others, and YOU WILL SUFFER FOR LIFE. Yes, the bad person will get exposed. But, that will be short-lived. Either the person (Seema, Sangeeta, Seema's old hag mausi, Charu etc.) will go back to their old ways of scheming or you will have to deal with another negative character.
Be a negative, scheming, good for nothing kinda creature and YOU WILL PROSPER by LEAPS AND BOUNDS every day. Yes, you will get exposed some day. But, WHO CARES? Family members have short-lived memory. They will accept you in a week or so and then you can CONTINUE with your scheming and plotting.
AWESOME SHOW.
Thank god that we have written updaters to save us from the misery of having to watch it.
