One my friend tells me she's passing through Guwahati, and gives me her mobile number so that I could call her once she's here.
I find it amusing-- the idea of someone from "Mainland India" carrying a mobile to this part of India, the north-eastern states. I carried mine when I came for a visit early this year, and it took a while for me to come to terms with it.
That the mobiles don't roam across the "border".
This is after all, a "special" area-- with special powers to army, specially detached from the nation..
