The building smelled like old paper and dead plants. I was on the night shift, three years now, cleaning offices in buildings that used to mean something. This one used to be a tech company. Or a data firm. I never learned the difference.

I pushed my cart down the hallway, past glass walls with fingerprints all over them. The fluorescent lights buzzed. Somewhere a pipe dripped. I unlocked the last office on the third floor and started where I always started. Under desks, behind chairs, in the corners where the dust settled thick.

That's when I saw it. Under a standing desk, half-hidden by a tangle of cables. A metal ball. Maybe six inches across. Heavy for its size. I picked it up, turned it over in my hands. Smooth surface, no marks, no seams. Just a ball. I figured it was some kind of paperweight or a piece of equipment from the old days. I tossed it in the recycling bag with the broken staplers and the empty coffee mugs.

By six in the morning I was done. Clock out. Walk to the bus stop. The ball sat at the bottom of the bag, heavy as a stone.

I didn't think about it on the bus. I didn't think about it at home, where the radiator clanked and the walls were thin enough to hear the neighbors fighting. I didn't think about it when I took the pills at 11 PM and stared at the ceiling until my eyes burned.

Two days later, I was at the scrap yard off I-75. You don't go there looking for anything but cash. The guy behind the counter. Tony, I think his name was. Weighed everything on a scale that had seen better decades. I dumped the bag. He sorted through the junk, nodded at a few things, then his hand stopped on the ball.

What's this? he asked.

Metal, I said.

He weighed it. Tapped it with his keys. Listened to the sound. Solid. Could be brass underneath. I'll give you forty-seven.

I nodded. Forty-seven dollars was forty-seven dollars. I took the bills, folded them, put them in my pocket. Walked out. Didn't look back.

That night, on the small TV in my apartment, the news talked about something called a knowledge storage device. Some tech company in Silicon Valley had lost one. Or stolen it. The reporter used words I didn't understand. Quantum encryption, classified data, intellectual property worth millions. I turned it off. The volume was too loud and my head hurt.

But the next morning, at the food bank, Maria's son asked me about it.

Earl, he said. He was ten years old, skinny, with eyes that didn't blink enough. What was that thing you sold?

I looked at him. He was holding a carton of milk like it was something precious. His mother stood nearby, sorting canned goods, her face lined with a kind of tired I recognized. We had talked at the food bank before. About nothing important. About the weather. About how the line was longer on Thursdays.

It was just metal, I said.

It looked important, the boy said.

I didn't answer. I couldn't.

Over the next week, I kept hearing things. Not from the news. I stopped watching that. But from people. At the supermarket where Maria worked, a man in line talked about how a scientist had been fired for trying to protect a device. At the bar where I sometimes went after night shift, two guys argued about a collector who had gone bankrupt chasing one. A government official was being investigated for hiding information about something called the sphere.

I didn't care. I told myself I didn't care. But I kept thinking about the boy's eyes. And about the weight of the ball in my hands.

I walked for three days. Three days across the city, from the food bank to the scrap yard, past storefronts with bars on the windows and churches with peeling paint. The scrap yard was on the other side of town, near the river, where the water looked black even in daylight.

Tony was there. He remembered me.

I want it back, I said.

He looked at me like I was crazy. That thing? I already sold it. To a buyer from out of state.

Can you get it back?

He shook his head. Not my call.

I stood there for a long time. Then I went home and took out every dollar I had. Forty-three dollars in my wallet. Twenty from the envelope I kept for Christmas. My son hadn't called in six months. I had saved the money anyway. Habit, I guess.

I went back to the yard. I gave Tony the money. He didn't say anything. He made a phone call. Came back an hour later.

Two hundred and fifty, he said. That's all I can do.

I gave him the rest. I didn't have more. I walked back to the food bank with the ball in a canvas bag. My legs ached. My hands were cold. I didn't stop.

At the entrance to the food bank, I set the bag down next to the donation bin. I wrote a note on the back of an envelope: Whoever wants it, take it. I don't care anymore.

I walked home. Turned on the TV. Sports news was on. Some game I didn't follow. I sat on the couch. The cushions were broken in a way that matched my body.

Maria came an hour later. She brought a dish in a plastic container. Pasta, she said. With tomatoes. We sat on the couch. Ate from the container with plastic forks. Didn't say much. Outside, a cleaner was sweeping leaves on the sidewalk. The ball sat at the food bank entrance, among thousands of donated cans and boxes, like a speck of dust. Nobody knew what it was. Nobody cared.

Maria finished her fork. Stood up. Said she had to go. I nodded. She left. I turned the TV up a little. The game went on. The cleaner outside kept sweeping.

I thought about the boy's eyes. Not because I was having an epiphany. I don't do those. Because the boy had asked a question, and I had given an answer that was true and not true, and that was the kind of thing that stayed with you, the way a splinter stays with you, small and annoying and impossible to ignore.

I thought about the scientist who had been fired. I thought about the collector who had gone bankrupt. I thought about the government official who had been investigated. All of them, caring about a metal ball they didn't understand, while I had sold it for forty-seven dollars and bought a pack of cigarettes and a lottery ticket and forgot about it.

There was no lesson in any of this. There was no meaning. The ball was just a ball. Maybe it was scrap brass. Maybe it was a piece of something important that someone else had already decided was more important than me. Maybe it was nothing at all.

I turned the TV up a little more. The game went on. The cleaner outside kept sweeping. The ball sat at the food bank entrance, among thousands of donated cans and boxes, like a speck of dust.

Nobody knew what it was. Nobody cared.

And that was that.
