So Neha tells us that Mehak wanted her to get her a doctor set. Neha refused saying she could use the one they already have, Palakh's. But Mehak, adamant to get one of her own, decided she would use her nani's kharchi to do so, conveniently forgetting that she bought a doll last week with that money. When she was reminded of that, she tried convincing Neha by pledging the kharchi she would get from her nani for her coming birthday. "No, that's not possible," Neha said so they struck a deal. Little Mehak has to earn 250 points if she wants to get a set. The rules are: 
She can't cry or hit Palakh unnecessarily. A broad smile gets a point. A glass of water she drinks gets a point. Wakes up at 7 without a fuss gets a point. Rude to Palakh, minus points. Hits Palakh, minus points.

So for the past two days she has stopped crying for silly things and every time she sees Neha she gives her a big, broad smile. She troubles Palakh but immediately says sorry, which she didn't before because, as Neha says, "of her BIG ego".
At the start of Day 3, Mehak had earned 13 points. Will she get to the 250? Meanwhile, Neha is loving it. "Mehak, o Mehak," she says.
