When I was growing up, Karachi was a place caught between ages, grasping at modernity while still clutching at the fading relics of an inglorious past. It was a city of skyscrapers and small, squat shanties. It had modern highways but was still pockmarked with peddlers wheeling vegetables over narrow dirt lanes on wooden carts. Imported luxury cars, rumbling, shining and glimmering in marvelous mechanical glory, were not uncommon, though neither was the pitifully obnoxious braying of overladen donkeys hitched to rickety wagons.
