She is correct

 John Smith and others were waiting in front of the emergency room for almost three hours. John Smith looked at Mrs Smith and Ronnie. They both slept in the place where they sit down.

'Looked like they have not slept nicely these days.' John Smith thought and reached Mrs Smith and wake her up.

"Grandma, you should go home with Ronnie and mom. I am here .Don't worry about Zinu. She will be fine. Dolly is alone there. She might need something."John Smith said.

"No John, maids are there. We don't want to go home." Alicia said.

"Yes. She is correct. How can I leave my granddaughter-in-law here, when she is in such danger?"Mrs Smith said annoyingly. 

"No mom. Look at grandma and Ronnie. They both are tired. Grandma would get ill if she sleeps here like this. Please grandma."John Smith said with a worried tone.

"Ok. Just call us, when the doctors will inform about her."Alicia said.
