Living in the UK, I notice how people are shy to talk about money, even in a non boastful way like to discuss investments, etc.
People love to whine just to start a conversation. Yes I am going to get flamed but I actually find it funny and I do like most people I've met.
I still have not figured out what to say to 'You're alright?' as a greeting after almost 10 years.
People are quite obsessed about social class.
I find this odd, but I hang around working class circles and the reverse snobbery is ugly. Many people I personally know would dislike you instantly if they know you have wealthy parents. It's almost like you can never truly be one of them even though it was ok before they knew your background.
This is not exclusively in the UK, but there are too many inconsiderate people talking in the cinemas. And the best part is very rarely anyone would confront them maybe because British people are too polite. I would tell them to shut up or call security.
You do love your tea! When tea bags run out at work, it is a crises.
So many young girls with babies in working class area and benefit system that traps people in poverty instead of empowering them with skills. If you are paid to stay at home, you will stay at home. I've known someone who quit his job after a day because he couldn't be bothered.
It is true that the Brits have one of the greatest sense of humour. It's one of the few things that keep me sane living in this country.
Just an observation, OP did ask..
