Childhood and literary fiction - Munro's stories

Reade the first section of Alice Munro's story Chaddeleys and Finleys (??), each section apparently about a group of her relatives, the first section, on the Ch's (her mother and her four aunts/mother's sisters) called Connection - I think this is the first story in The Moons of Jupiter, and I read it in the 1996 Selected Stories, which is giving me a great retrospective view of Munro's career. This story is essentially in two parts - the first involving the visit of the four sister's to the narrator's (obviously, Munro's) western Ontario home during the summer - the young narrator fascinated by the flamboyant and enthusiastic sisterly affection among the five, recollecting in great detail the dinners, conversations, and rural entertainments (a berry-picking excursion, e.g.) - then a brief retrospective on the four sisters and why this was the only extended group visit - one died shortly afterwards - and then the story moves into its second phase, the narrator now a grown woman married to a wealthy attorney and living on a mountainside in Vancouver, the marriage strained to near the breaking point - and one of the aunts stops by for a visit as part of a trip to Alaska with other widows and never-weds, mostly women. The dinner visit is awkward in the extreme, and the husband makes no attempt to be genial, generous (won't even give the aunt a ride back to her hotel), or gracious, and follows the dinner with nasty critique of the aunt's accent, ignorance, boorishness and so forth - until narrator throws a dish or glass at him, barely missing - and this explosive action, a defense of her family and in a sense herself, not wanting to feel shame about her family origin, not participating in her husband's pile-on of insults, is obviously a pivotal moment in the marriage. It strikes me in reading this story how incredibly important childhood memories are to our greatest writers - the exquisite details with which Munro, Updike, Roth, as three examples of literary fiction in the naturalistic mode, recall and depict their childhood, including family dynamics, social strata, and sense of place, is no doubt the hallmark of each of the three and many others - which shows of course that childhood is always with us, the child is father to the man (or mother to the woman, so to speak), and our great writers help us understand, comprehend that, each in his or her own way and style.
