He was a fellow Bengali from Calcutta who had washed up on the barren shores of my parents’ social life in the early seventies, when they lived in a rented apartment in Central Square and could number their acquaintances on one hand. But I had no real uncles in America, and so I was taught to call him Pranab Kaku. Accordingly, he called my father Shyamal Da, always addressing him in the polite form, and he called my mother Boudi, which is how Bengalis are supposed to address an older brother’s wife, instead of using her first name, Aparna. After Pranab Kaku was befriended by my parents, he confessed that on the day we met him he had followed my mother and me for the better part of an afternoon around the streets of Cambridge, where she and I tended to roam after I got out of school. He had trailed behind us along Massachusetts Avenue and in and out of the Harvard Coop, where my mother liked to look at discounted housewares. He wandered with us into Harvard Yard, where my mother often sat on the grass on pleasant days and watched the stream of students and professors filing busily along the paths, until, finally, as we were climbing the steps to Widener Library so that I could use the bathroom, he tapped my mother on the shoulder and inquired, in English, if she might be a Bengali.
