From the New York Times:
A few minutes before 7 on a recent morning, Greeshma Salin swiveled her chair to face the computer, slipped on her headset and said in faintly accented English, “Hello, Daniela.” Seconds later she heard the response, “Hello, Greeshma.”
The two chatted excitedly before Ms. Salin said, “We’ll work on pronouns today.” Then she typed in, “Daniela thinks that Daniela should give Daniela’s horse Scarlett to Daniela’s sister.”
“Is this an awkward sentence?” she asked. “How can you make it better?”
Nothing unusual about this exchange except that Ms. Salin, 22, was in Cochin, a city in coastal southern India, and her student, Daniela Marinaro, 13, was at her home in Malibu, Calif.
