Yeah the book thing is nonsense, it’s an old stereotype; like old money wearing old clothes and driving beat up cars. Life isn’t a jilly cooper novel. The middle classes read on iPads or kindles. It’s lower working class who are more likely to have paperbacks, and upper middle class now, with libraries. Books are not something people have cluttering their homes now, if they can afford it, it’s done electronically. Sure some middle class do, but its not the norm any more.
we are solidly middle class. In a much grander house than the op is asking about and we do have books, a few hardbacks on the coffee table, that are browsed, biographies etc, and we have books , in a closed cupboard, we wish to keep, they aren’t displayed, generally reading is done electronically, and it’s the same for all our friends.
