I wrote your information to my former forster son in Manipur. This is his answer:
"Well, it makes me surprise to know that Tibetan’s language and our language is similar. This makes me think of my past in Derah-Dun. I came across many Tibetan people who speak different languages even we can’t communicate each other. But I haven’t seen their script."
I like to meet him, but his wife doesn't speak English. I like to communicate with her.
