Ok, this guy from Darjeeling who slept on the berth just beneath me last night thinks these two girls must be from Shillong. [Later, at the near end of the travel, I learned that the girls are from Manipur.]
The Ghale guy from Daejeeling. His name is Bikash Ghalay, I learned later. We started speaking in Nepali from the moment we knew the other guy was a Nepali. Bikash is 27 and says his parents have been suggesting him to find a girl from “afno jaat” and marry. He is looking for a Ghale girl. “Hamro tira kam 6 ghale kt haru (there r very few Ghale girls on our side)” he said. I suggested him to go to Nepal (Kaski, Lamjung) and find one.
He is sleeping now. So are the girls. Same with the sasu-buhari pair.
