Sitting here in New Delhi, not having been to Calcutta for two years, I sometimes get homesickness attacks. The first sign that one of these seizures is coming on is when I find myself muttering imprecations about Punjabis, Haryanvis, UP-wallas and other North Indians, including pompous Delhi-Madrasi bureaucrats, in my rusty street Bangla. One of the first curses that comes to my tongue is the old favourite ‘Boka!" (unintelligent fornicator), followed by the sexist but immensely satisfying ‘Khanki’r bachhara’ (children of whores).
