These are conversation topics for boring people, not ''middle class topics''...
Frankly in the time we live in there is plenty to talk about.
Don't these people have passions, hobbies, beliefs, jobs that go beyond the pathologically mundane?
Don't they ever go to see films, exhibitions, any other cultural event?
I am middled aged and interested in art, films, music feminism, horses, books, why the hell the Tories are still in power, fashion, fighting racism, , climate change and many more topics....
I would not want to socialise with people who only want to talk about the size of their house, their kids' school or what is and isn't middle class all the time... It just seems incredibly inward-looking.
