. . . she herself brought it up by saying in the interview that the 5 dogs "don't even make that much noise", so they have to be pretty noisy and she knows that it could be annoying or she wouldn't have even mentioned the dogs.
Good point about the lady's remark. She does seem to be accidentally admitting that her dogs are very noisy! It could turn out that the neighborhood is just your regular noisy neighborhood with kids and dogs and lawnmowers and all, but that the girls' noise went far beyond what could be reasonably tolerated. No matter what, though, I will always picture this woman as looking and dressing like Mrs. Drysdale
I think the newspaper used the term "posh" on purpose to describe this neighborhood of plumbers, above-ground pools, and lots of family pets because it makes the story more dramatic -- mean old Mrs. Drysdales trying to destroy the happiness of little girls and imprison their parents.
Now, if the town had actually sent the parents to jail -- that would have been ridiculous!
