I seem to have worked my way down to working class (retired).
My parents and siblings I'd describe as middle class. All went to grammar/boarding school, (including myself), and most have degrees. All own their own homes. All have a good standard of living and good jobs.... except me.
People tell me that I talk 'posh' Yorkshire, but I'm pretty much potless, and live in a council bungalow. Sometimes vote Labour, sometimes Conservative.
The original Black Sheep, I'd say.
