The box had been leaning against the living room wall for three weeks.

It was a dresser. Ellis Vance had bought it on a Saturday in a fit of intent, and had been walking around it ever since.

Six drawers, birch veneer, ninety-nine dollars. It was heavier than a box that size had any right to be. He had carried it up two flights by himself, stopping once on the landing to change his grip, and stood it against the wall between the radiator and the bookcase. He was tall, which had helped, and not especially strong, which had not. It had been there long enough that the carpet under one corner had gone flat.

Every few days he moved a jacket off the top of it. Once he had set a bag of groceries down on it on his way in and left them there long enough that the ice cream came out of the carton as soup. That was the whole relationship they had.

It was a Tuesday in April and it was still light at seven. Buffalo had spent five months being Buffalo and had finally stopped. He came home, ate a sandwich standing at the counter, and looked at the box.

Tonight he opened it.

He cut the tape with a kitchen knife and folded the flaps back, and everything came out onto the carpet in the order the manual wanted. Panels first, stacked flat, each one in a sleeve of gray foam. Then the rails. Then the little bags of hardware, four of them, taped to a rectangle of cardboard.

The instructions had no words in them at all. Just a cartoon man with a dot for a face, holding up parts and looking pleased about it. On the third page the cartoon man had a friend, helping him lift something. The friend did not appear again.

There was an allen wrench the size of his thumb.

He counted the hardware against the parts list, which he had never once done before in his life. Fourteen cam locks. Twenty-eight dowels. Two bags of screws in two lengths, and a smaller bag of the black ones for the back panel. It took four minutes.

It turned out to be right. He had assumed it would not be, and it was, and that was somehow the best part of the evening so far.

He got the third step wrong.

He had the left side panel in backwards. He did not notice for four more steps. By then he had two rails and a drawer runner mounted on it, and he had turned the whole assembly over twice to get at the back of it.

What told him was the holes.

There are pre-drilled holes on the inside face of every panel and none at all on the outside. That is how flat-pack furniture works. You never see a hole once the thing is together. He was looking at a clean stretch of birch where a row of holes should have been, and there was no version of this where that was correct.

He sat back on the carpet and looked at it for a while. The radiator ticked. Somebody upstairs ran water.

Then he counted forward through the manual to work out how far back he would have to go. Four steps. He counted it a second time, because the first time he had wanted a different answer.

He could have left it.

The dresser would have stood up fine. It would have been a dresser with one panel in backwards and a row of empty holes facing out, against a wall, in a room that nobody but him ever came into. The panel was structural either way. Nothing about it would ever have failed. It would have held socks for ten years.

No human being would have known. He lived alone. There was no inspection coming.

He took it apart instead.

Four steps back, one screw at a time. He laid each piece down on the carpet in the order it came off. Beside each piece he set that piece's own screws. He had learned that much the hard way on other projects.

Then he turned the panel around, put it in the right way, and did the four steps over.

It took forty minutes. Objectively, it was forty minutes that did not need to be spent.

At eleven-forty he stood the thing up.

It was square. He put a hand on the top corner and pushed, and it did not rock. He crouched down and sighted along the front and the gaps between the drawer faces were even all the way down.

He pulled each drawer out and slid it back in. Every one of them ran clean.

He was much happier about this than a ninety-nine dollar dresser warrants. He stood in the middle of his own living room at twenty to midnight, looking at a piece of furniture, pleased.

There were two screws left over.

They were sitting on the carpet by his knee. Short ones, black, the kind that go into the back panel. He picked them up and turned them over on his palm. They were from this box. There was no question about that.

So he picked the manual back up.

He went through it page by page, forward and then backwards, checking every place a screw that size could have gone. He counted the screws already in the back panel and got exactly the number the manual showed. Six or seven minutes of this, on a dresser that was already built and already solid.

He never found where they went.

He shook it again, harder this time, with both hands on the top. Nothing moved.

So he carried the two screws into the kitchen and opened the drawer by the sink and dropped them in with the rest.

There was a lot of rest. Allen keys from four different things, all of them slightly different sizes. Plastic dowels. Cam locks. A single washer he had never been able to place. A pile of screws from every object he had ever assembled, sitting in the dark, unused and paid for.

He shut the drawer with his hip and did not think about it again.

Around him the apartment held the evidence of everything else he had picked up and put down.

A bread machine on top of the fridge, still plugged in, not used since March. He had made nine loaves in three weeks and every one of them had come out better than the last, and then he had stopped, and he could not have told anybody why.

Climbing shoes by the door, still holding the shape of his feet. A model destroyer three-quarters built on the desk under the window, the rest of its parts sorted by size into a takeout container by a version of himself who had believed in the project.

He had started going to the gym four separate times. He had enjoyed all four.

None of it embarrassed him, exactly.

He had worked something out about himself years ago and had never said it out loud to anyone, because saying it would have made it sound worse than it was.

He liked the beginning of things. He liked the part where you go from knowing nothing to knowing a little. Where an hour of effort buys you something you can actually see.

He liked watching a number move.

The loaves got better. The routes at the gym went up a color. The weight on the bar climbed every week for two months, and then every three weeks, and then it stopped being interesting, and he found something else that was.

He had never once found the thing he wanted badly enough to keep going after the easy part ran out.

He was not unhappy about it, either. People got that wrong, looking at a life like his from the outside. He was not sitting in a ruin. He had a job he was good at, an apartment he liked, and two older sisters who called him more than he called them. He had been comfortable for a long time.

He had dark curly hair that he kept short because it did what it wanted otherwise, and a beard he kept trimmed because the alternative required a decision every morning. His left eyebrow sat a little higher than the right. It made people think he was surprised by them, which he mostly was not.

He was thirty-four. He assumed that was the whole story.

On his way to bed he passed the second monitor.

A news tab had been open on it since that morning. He had opened it at work, read the headline, and left it there.

A lab outside Grenoble had been running a simulation on a quantum computer. Something had come out of the machine that nobody had put into it. Eleven photons. Real light, measured, out of a piece of space that was supposed to be empty.

There was a photo of six tired people standing in front of a machine that looked like a water heater wearing a cage. The writer called the result promising but of limited near-term use.

Ellis read the first paragraph. It was about pulling energy out of empty space, which sounded like nonsense and apparently was not. He read most of the second one. It used the word decoherence twice without explaining it either time, and he decided he would read the rest tomorrow.

He turned off the light.

He would not read the rest tomorrow.

Nineteen days later he would be standing in a hall he had no name for, a very long way from Buffalo, with nine thousand eight hundred eleven other people. Most of them held a world record, or a patent, or a rank, or a title. Several of them had killed people as part of their work. One of them had a Fields Medal.

He would be the only one in the room who had spent a recent evening genuinely happy about a dresser.
