At five forty, the building belonged to Teresa. By eight thirty, it would belong to people who hurried past her cart while looking at their phones. She liked the earlier version. The elevator answered immediately. Nobody apologized for needing to step around her mop and then stepped into the wet patch anyway.

She cleaned the third floor first because the accountants arrived early. Someone in the corner office had started leaving an orange peel in a mug. Teresa had developed a private, uncharitable opinion of this person. On Monday she found the mug washed and upside down by the sink, and revised her opinion a little.

The earring appeared under a conference table on Tuesday. It was small, a silver leaf with a bent post. Teresa put it in an envelope and left it at reception. By Thursday the envelope was still there, half hidden under a delivery clipboard. She moved it where it could be seen.

On Friday a woman came looking for her. Teresa recognized the expensive coat but not the worried face above it.

“You found it?” the woman asked.

“Under the big table.”

“I thought I'd lost it on the train.” She closed her hand around the envelope. “My sister gave me these. Before she died.”

There was no useful reply to that except, “I'm glad it's back.” Teresa said it and meant it.

The woman introduced herself as Helen. She asked Teresa's name, then repeated it carefully. People did this sometimes when they wanted to show they were nice. Teresa waited for the conversation to finish. Instead, Helen asked what time she started.

“Five thirty.”

“Every day?”

“The floors don't take Thursdays off.”

Helen laughed. Teresa did too. It was the first thing they had said to each other that did not feel fragile.

A week later, Helen held the elevator while Teresa maneuvered her cart through the door. Another week later, a junior employee stopped stacking heavy boxes against the cleaning cupboard. Small improvements, not a revolution. Teresa's back still ached on Fridays, and the building manager still needed three reminders to order decent gloves.

At church, she sometimes heard people talk about finding their calling. The examples tended to involve teaching, medicine, or traveling somewhere far away. She wondered whether a calling could involve replacing paper towels. She did not want to romanticize work that deserved better pay. She wanted to be able to respect the hours that made up her days.

One morning she stood in the empty reception area after finishing the glass doors. Pale light stretched across the floor. In twenty minutes, someone would spill coffee on it. For now, it was clean because she had made it clean. There was no applause, but there was an actual good thing where a mess had been.

She thought about the instruction to work wholeheartedly. She had once heard it as a demand to work harder without complaint. Lately she wondered if it could also mean this: her work had worth even when the people benefiting from it forgot to notice. And because it had worth, she could ask for gloves, fair hours, and a little consideration.

When Helen arrived, she lifted a hand in greeting. Teresa pointed at the floor.

“Other door today. This one's still wet.”

Helen went around. Teresa moved the yellow sign a few inches into the light.
