She could picture them with perfect clarity. Sanaa narrating the entire flight to whoever sat nearest β the takeoff, the clouds, the pretzels, a full documentary. Zola watching everything, saying nothing, until the exact moment it mattered. They would be fine. They were Ellis girls. They were nine β almost β and they were braver than anyone gave them credit for.
But Monica had been a nurse for fourteen years, and she had sat with enough frightened children in enough curtained bays to know that brave and fine were not the same thing. Brave was what you were on the outside. Fine was what somebody made sure of. And she was not sending her daughters into the sky on their ninth birthday with nothing but brave.
She opened the airline's website and looked at the seat map.
The twins' tickets were in the back of the plane, two middle seats, three rows apart β booked in February, when "together" had meant "on the same flight," which had seemed like enough. It was not enough. Not now. She clicked through to the change-seats page, and the page loaded slowly, the little airplane icon spinning, and while it loaded she thought about the savings account.
She had opened it when the girls were four. Eleven dollars a week, every week, automatic transfer every Friday, the kind of money you didn't miss because you never saw it. The bank had let her name the account, and she had named it NINE, because nine had seemed impossibly far away then, a joke about the future, a round number with two girls in it. The future was eleven days away now. She knew the balance the way she knew the girls' shoe sizes β she checked it the way other people checked the weather β and she did the arithmetic in her head before the seat map even finished loading.
The seat map resolved. The forward cabin β the airline called it something fancier on the website, but Monica had flown enough, and worked enough red-eyes, to know it was just the front of the plane, where the flight attendants lived during the flight, where a crew member could see two small girls without walking the length of the aircraft. Two seats together. Window and middle. Sanaa would take the window β she had already claimed it, months ago, in the hypothetical, with the ferocity of a firstborn β and Zola would take the middle, pressed against her sister, which was where Zola liked to be anyway, in the orbit of noise.
Four hundred and eighty-one dollars, to move them both.
She sat very still.
Four hundred and eighty-one dollars was forty-three weeks of eleven dollars. Almost a year of the NINE account. It was the new tires the car needed β the front left was going bald, she had been watching it. It was two months of Esther's supplemental prescriptions, the ones insurance argued about, the ones that came in the white bag with the stapled receipt. It was the birthday party she had been planning before the fall β the one with the real cake from the bakery on Central, the one the girls had been describing to anyone who would listen since October.
It was her daughters, nine years old, flying alone on their birthday, where the crew could see them.
She moved the seats.
She typed the card number from memory β the savings account debit card, the one she almost never used, the numbers worn smooth in her mind from the two times she had β and she did not hesitate, because hesitation was a luxury and she had stopped affording luxuries around the time the twins learned to walk. The confirmation email arrived with a soft chime that sounded too cheerful for midnight. SEATS UPDATED, it said. She read it twice. Then she wrote the number in the notebook, in the column, and drew a small box around it, the way she did for numbers that were decided.
Then she looked at the birthday-cake doodle in the margin, and she had the idea.
It came the way her best ideas came β sideways, while she was looking at something else. The girls had been born at 4:41 and 4:45 in the afternoon, and every year on the fourteenth, at 4:41 exactly, Monica stopped whatever she was doing and called them to her. At school pickup, at the dinner table, once in a grocery store parking lot with the cart still rolling β "Nine years ago this minute," she would say, and they would shriek, because the minute was the thing, the minute was theirs. Sanaa always claimed the minute belonged to her more. Zola always said, "Four minutes later, I made it better," and Sanaa always shrieked louder, and Monica always laughed until her face hurt.
