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).
