Genuinely don't know what class I am.
My mum was the daughter of a senior army officer and had a private school education. My dad was the son of Irish immigrants, his dad worked in construction, and Mum was a school cook.
Mum rebelled and married my dad. Ended up in a council house which they bought in the 1980s. I am state school educated (albeit with a grandpa who taught me Latin and Greek every Saturday morning)
I now have post grad qualifications and earn £90k, DH earns more. Both of our kids went to good state grammar schools and are at university. We have a really good standard of living and enjoy lots of culture, theatre, art, music etc.
My mum thinks I am a snob because I like culture, have a detached house and do a very middle-class job.
My MIL thinks I am not worthy of her son because I grew up in a council house so I must be very working class.
Colleagues think I am posh because of the culture I enjoy, and they were stunned when I did an archaeological dig last year as they thought that was ridiculously posh.
BBC class survey thinks I am an 'elite'
All I can conclude is that class is something that other people pigeonhole you as.
