He told her that he and his wife had adopted a black child and their neighbors looked at them as though they had chosen to become martyrs for a dubious cause. Her blog post about him, "Badly-Dressed White Middle Managers from Ohio Are Not Always What You Think," had received the highest number of comments for that month. She still wondered if he had read it. She hoped so. Often, she would sit in cafés, or airports, or train stations, watching strangers, imagining their lives, and wondering which of them were likely to have read her blog. Now her ex-blog. She had written the final post only days ago, trailed by two hundred and seventy-four comments so far. All those readers, growing month by month, linking and cross-posting, knowing so much more than she did; they had always frightened and exhilarated her. SapphicDerrida, one of the most frequent posters, wrote: I'm a bit surprised by how personally I am taking this. Good luck as you pursue the unnamed "life change" but please come back to the blogosphere soon. You've used your irreverent, hectoring, funny and thought-provoking voice to create a space for real conversations about an important subject. Readers like SapphicDerrida, who reeled off statistics and used words like "reify" in their comments, made Ifemelu nervous, eager to be fresh and to impress, so that she began, over time, to feel like a vulture hacking into the carcasses of people's stories for something she could use. Sometimes making fragile links to race. Sometimes not believing herself. The more she wrote, the less sure she became. Each post scraped off yet one more scale of self until she felt naked and false.

The ice-cream-eating man sat beside her on the train and, to discourage conversation, she stared fixedly at a brown stain near her feet, a spilled frozen Frappuccino, until they arrived at Trenton. The platform was crowded with black people, many of them fat, in short, flimsy clothes. It still startled her, what a difference a few minutes of train travel made. During her first year in America, when she took New Jersey Transit to Penn Station and then the subway to visit Aunty Uju in Flatlands, she was struck by how mostly slim white people got off at the stops in Manhattan and, as the train went further into Brooklyn, the people left were mostly black and fat. She had not thought of them as "fat," though. She had thought of them as "big," because one of the first things her friend Ginika told her was that "fat" in America was a bad word, heaving with moral judgment like "stupid" or "bastard," and not a mere description like "short" or "tall." So she had banished "fat" from her vocabulary. But "fat" came back to her last winter, after almost thirteen years, when a man in line behind her at the supermarket muttered, "Fat people don't need to be eating that shit," as she paid for her giant bag of Tostitos. She glanced at him, surprised, mildly offended, and thought it a perfect blog post, how this stranger had decided she was fat. She would file the post under the tag "race, gender and body size." But back home, as she stood and faced the mirror's truth, she realized that she had ignored, for too long, the new tightness of her clothes, the rubbing together of her inner thighs, the softer, rounder parts of her that shook when she moved. She was fat.

She said the word "fat" slowly, funneling it back and forward, and thought about all the other things she had learned not to say aloud in America. She was fat. She was not curvy or big-boned; she was fat, it was the only word that felt true. And she had ignored, too, the cement in her soul. Her blog was doing well, with thousands of unique visitors each month, and she was earning good speaking fees, and she had a fellowship at Princeton and a relationship with Blaine—"You are the absolute love of my life," he'd written in her last birthday card—and yet there was cement in her soul. It had been there for a while, an early morning disease of fatigue, a bleakness and borderlessness. It brought with it amorphous longings, shapeless desires, brief imaginary glints of other lives she could be living, that over the months melded into a piercing homesickness. She scoured Nigerian websites, Nigerian profiles on Facebook, Nigerian blogs, and each click brought yet another story of a young person who had recently moved back home, clothed in American or British degrees, to start an investment company, a music production business, a fashion label, a magazine, a fast-food franchise. She looked at photographs of these men and women and felt the dull ache of loss, as though they had prised open her hand and taken something of hers. They were living her life. Nigeria became where she was supposed to be, the only place she could sink her roots in without the constant urge to tug them out and shake off the soil. And, of course, there was also Obinze. Her first love, her first lover, the only person with whom she had never felt the need to explain herself. He was now a husband and father, and they had not been in touch in years, yet she could not pretend that he was not a part of her homesickness, or that she did not often think of him, sifting through their past, looking for portents of what she could not name.
