That's a new term I've learnt watching these serials!
I'm referring to Nikhila and Shiv's b'day wishes to Gauri. They actually wished her "Many happy returns of the day!'
How could they, when they knew her days are numbered and that she won't live to see her next birthday??!!
I find that very cruel and in bad taste. Hope Gauri brings up this horrible irony when she and Shiv meet up in the bed room on Monday...at least, I hope he's going to the bed room to apologise.
