Because he played the part of a younger brother, she felt free to call him Pranab, whereas she never called my father by his first name. My father was thirty-seven then, nine years older than my mother. Pranab Kaku was twenty-five. My father was a lover of silence and solitude. He had married my mother to placate his parents; they were willing to accept his desertion as long as he had a wife. He was wedded to his work, his research, and he existed in a shell that neither my mother nor I could penetrate. Conversation was a chore for him; it required an effort he preferred to expend at the lab. He disliked excess in anything, voiced no cravings or needs apart from the frugal elements of his daily routine: cereal and tea in the mornings, a cup of tea after he got home, and two different vegetable dishes every night with dinner. He did not eat with the reckless appetite of Pranab Kaku. My father had a survivor's mentality. From time to time, he liked to remark, in mixed company and often with no relevant provocation, that starving Russians under Stalin had resorted to eating the glue off the back of their wallpaper. One might think that he would have felt slightly jealous, or at the very least suspicious, about the regularity of Pranab Kaku's visits and the effect they had on my mother's behavior and mood. But my guess is that my father was grateful to Pranab Kaku for the companionship he provided, freed from the sense of responsibility he must have felt for forcing her to leave India, and relieved, perhaps, to see her happy for a change.
In the summer, Pranab Kaku bought a navy-blue Volkswagen Beetle and began to take my mother and me for drives through Boston and Cambridge, and soon outside the city, flying down the highway. He would take us to India Tea and Spices in Watertown, and one time he drove us all the way to New Hampshire to look at the mountains. As the weather grew hotter, we started going, once or twice a week, to Walden Pond. My mother always prepared a picnic of hard-boiled eggs and cucumber sandwiches and talked fondly about the winter picnics of her youth, grand expeditions with fifty of her relatives, all taking the train into the West Bengal countryside. Pranab Kaku listened to these stories with interest, absorbing the vanishing details of her past. He did not turn a deaf ear to her nostalgia, like my father, or listen uncomprehending, like me. At Walden Pond, Pranab Kaku would coax my mother through the woods, and lead her down the steep slope to the water's edge. She would unpack the picnic things and sit and watch us as we swam. His chest was matted with thick dark hair, all the way to his waist. He was an odd sight, with his pole-thin legs and a small, flaccid belly, like an otherwise svelte woman who has had a baby and not bothered to tone her abdomen. "You're making me fat, Boudi," he would complain after gorging himself on my mother's cooking. He swam noisily, clumsily, his head always above the water; he didn't know how to blow bubbles or hold his breath, as I had learned in swimming class. Wherever we went, any stranger would have naturally assumed that Pranab Kaku was my father, that my mother was his wife.
It is clear to me now that my mother was in love with him. He wooed her as no other man had, with the innocent affection of a brother-in-law. In my mind, he was just a family member, a cross between an uncle and a much older brother, for in certain respects my parents sheltered and cared for him in much the same way they cared for me. He was respectful of my father, always seeking his advice about making a life in the West, about setting up a bank account and getting a job, and deferring to his opinions about Kissinger and Watergate. Occasionally, my mother would tease him about women, asking about female Indian students at MIT or showing him pictures of her younger cousins in India. "What do you think of her?" she would ask. "Isn't she pretty?" She knew that she could never have Pranab Kaku for herself, and I suppose it was her attempt to keep him in the family. But, most important, in the beginning he was totally dependent on her, needing her for those months in a way my father never did in the whole history of their marriage. He brought to my mother the first and, I suspect, the only pure happiness she ever felt. I don't think even my birth made her as happy. I was evidence of her marriage to my father, an assumed consequence of the life she had been raised to lead. But Pranab Kaku was different. He was the one totally unanticipated pleasure in her life.
In the fall of 1974, Pranab Kaku met a student at Radcliffe named Deborah, an American, and she began to accompany him to our house. I called Deborah by her first name, as my parents did, but Pranab Kaku taught her to call my father Shya-mal Da and my mother Boudi, something with which Deborah gladly complied. Before they came to dinner for the first time, I asked my mother, as she was straightening up the living room, if I ought to address her as Deborah Kakima, turning her into an aunt as I had turned Pranab into an uncle. "What's the point?" my mother said, looking back at me sharply. "In a few weeks, the fun will be over and she'll leave him." And yet Deborah remained by his side, attending the weekend parties that Pranab Kaku and my parents were becoming more involved with, gatherings that were exclusively Bengali with the exception of her. Deborah was very tall, taller than both my parents and nearly as tall as Pranab Kaku. She wore her long brass-colored hair center-parted, as my mother did, but it was gathered into a low ponytail instead of a braid, or it spilled messily over her shoulders and down her back in a way that my mother considered indecent. She wore small silver spectacles and not a trace of makeup, and she studied philosophy. I found her utterly beautiful, but according to my mother she had spots on her face, and her hips were too small.
For a while, Pranab Kaku still showed up once a week for dinner on his own, mostly asking my mother what she thought of Deborah. He sought her approval, telling her that Deborah was the daughter of professors at Boston College, that her father published poetry, and that both her parents had PhDs. When he wasn't around, my mother complained about Deborah's visits, about having to make the food less spicy, even though Deborah said she liked spicy food, and feeling embarrassed to put a fried fish head in the dal. Pranab Kaku taught Deborah to say khub bhalo and aacha and to pick up certain foods with her fingers instead of with a fork. Sometimes they ended up feeding each other, allowing their fingers to linger in each other's mouth, causing my parents to look down at their plates and wait for the moment to pass. At larger gatherings, they kissed and held hands in front of everyone, and when they were out of earshot my mother would talk to the other Bengali women. "He used to be so different. I don't understand how a person can change so suddenly. It's just hell-heaven, the difference," she would say, always using the English words for her self-concocted, backward metaphor.
The more my mother began to resent Deborah's visits, the more I began to anticipate them. I fell in love with Deborah, the way young girls often fall in love with women who are not their mothers. I loved her serene gray eyes, the ponchos and denim wrap skirts and sandals she wore, her straight hair that she let me manipulate into all sorts of silly styles. I longed for her casual appearance; my mother insisted whenever there was a gathering that I wear one of my ankle-length, faintly Victorian dresses, which she referred to as maxis, and have party hair, which meant taking a strand from either side of my head and joining them with a barrette at the back. At parties, Deborah would, eventually, politely slip away, much to the relief of the Bengali women with whom she was expected to carry on a conversation, and she would play with me. I was older than all my parents' friends' children, but with Deborah I had a companion. She knew all about the books I read, about Pippi Long-stocking and Anne of Green Gables. She gave me the sorts of gifts my parents had neither the money nor the inspiration to buy: a large book of Grimm's Fairy Tales with watercolor illustrations on thick, silken pages, wooden puppets with hair fashioned from yarn. She told me about her family, three older sisters and two brothers, the youngest of whom was closer to my age than to hers. Once, after visiting her parents, she brought back three Nancy Drews, her name written in a girlish hand at the top of the first page, and an old toy she'd had, a small paper theater set with interchangeable backdrops, the exterior of a castle and a ballroom and an open field. Deborah and I spoke freely in English, a language in which, by that age, I expressed myself more easily than Bengali, which I was required to speak at home. Sometimes she asked me how to say this or that in Bengali; once, she asked me what asobbho meant. I hesitated, then told her it was what my mother called me if I had done something extremely naughty, and Deborah's face clouded. I felt protective of her, aware that she was unwanted, that she was resented, aware of the nasty things people said.
