Life can be full of surprises and some of these can even turn out to be very pleasant ones. Last month at Geneva airport when I handed over my passport to the immigration officer, he started speaking in fluent Hindi. When I asked him how come, he said he had spent many years in ­Hindustan. From his accent I could say he was from Afghanistan. But I didn’t ask because that would have been rude. His friendliness was in stark contrast to the usually grim ways of immigration officials. It reflects the unfriendly immigration policies of all governments.
