What is the author's style in Blackberry Winter by Robert Penn Warren?

The story is told by a first-person narrator who is recalling events that happened to him sometime in the past. Not until the epilogue does he reveal that thirty-five years separate the events of that June day from the narration. This distance sets up a contrast between the nine-year-old Seth's point of view and the forty-four-year-old narrator's. This structure not only invites comparison between the boy's perception of events and the man's, it also asks readers to consider how the mechanism of memory works. In other words, is it the events of that June day that are important, or the recollection of those events over the intervening time period?
