Clues in the scene
arrives the day after the event.
The reply comes after the information was needed, making timing the decisive clue.
Each choice explained
Mild dissatisfaction with a reply arriving too late — Best fit
The meeting was over before the location reply arrived. The ageing metaphor can express mild dissatisfaction with the delay.
Admiration for the reply's depth — Does not fit
No depth or excellence of the answer is described. The scene supplies its timing, not evidence of admiration.
A preference for next-day replies in future — Does not fit
No request for future next-day replies appears. That reverses a joke about this delay into a desired practice.
An announcement that the meeting place changed — Does not fit
The location is not said to have changed. A late reply about a location is not a change notice.
Same words, another scene
Friends agree to take time over thoughtful replies to a book discussion. A long response arrives within their agreed period, and one adds the same joke.
The ageing metaphor can now playfully acknowledge time spent thinking. The agreed response window, not the metaphor alone, determines whether lateness is a problem.
Reading it slowly gave me these thoughts. Thank you for the detailed response.
Literal meaning
A fictional metaphor treating a reply as something that needs time to mature.
What these words cannot tell us
Why the answer was late, how annoyed the speaker is or whether the delay was intentional is unknown.
A question to ask in real life
This time I needed the answer before we met. When could you check a similar message next time?
