Well. I don't know what I am then, having read this thread. My dad's parents were immigrant Irish to Glasgow and then later Coventry. My mum's parents are (still alive) a retired doctor (Granny) and partner in firm of accountants. My mum and dad met at church youth group.
My dad went to Oxford university and is a secondary (independent) school teacher. My mum was a nurse and then HV til she retired last year.
My brothers and I went to independent schools. I am a primary school teacher, with very good GCSEs, "A" levels and undergrad degree in English and Spanish from a red brick uni. One brother is a university lecturer with a first class degree and d.Phil from the same college as my dad. Another is a (reformed) criminal, who has spent time in prison and now teaches TEFL abroad.
My partner's parents are, in his dad's case, a market trader, warehouseman, window cleaner and other jobs, his mum a SAHM/cleaner. My partner got a better degree than me from a better university, from a comprehensive, and is also a teacher. His brother is a plumber, and his sister a care home worker.
No idea where we all fit in!
