Is usually pretty easy to place people into these virtual class slots by listening to language..
Upper class have a granny
Middle class a grandma
Working class a nan or nanny
For upper class nanny looks after your children and is definitely not your mil or dm. !
Working class read red top paper if at all
Lower middle (with aspirations to upper middle) - the daily mail.
Upper middle - The guardian
Upper - The times or Telegraph.
They working class have breakfast, dinner then tea.
The middle class have breakfast, Lunch then Supper
The upper class have Breakfast, Lunch, Dinner then Supper (after the theatre)
The upper class care little about cleaning their homes (as others do that ) or the latest furnishings. Much more likely to have a few really expensive pieces expected to last many years until they fall apart. The greatest horror would be for anyone to assume they were nouveau riche.. it's about 'old money' (which is NEVER discussed).
