The general jist of BD complaints are that things were better with Osea when Jeremy and his parents were around. Than under the relatives. It's just an observation.
Going back to her time there, it was a very different place to the one which exists now. I very much doubt that Nevill would have allowed old vans, past their sell by date, to grace the front row, and as sure as God made little green apples, JB, with his love of money, certainly wouldn't have, but BD never got to know that because, at the time, JB was only helping hand.
