The brits like an understatement. the americans like a BIG statement.
the british can use an affectionate insult and do often, there is no such thing in america
I think americans are polite, pretty loud but then the british can be loud as well depending on the group
we're all about the booze wheras the americans have more of a clean living type attitude.
americans are confident and imo generally good communicators. the british are more reserved.
americans are more likely to freely express emotion wheras we can't think of anything worse than laying it all out (mostly)
i think there are a lot more subtitles in the english language and subtleties in society in general than in american society in terms of social class. I think americans have crafted their country to be logical wheras we have many quirks which don't make too much sense.
and they hold 'world international' sports competitions which only they are entered in hahaha
We're a nation of cynics, there's a kind of pride and belief in their country which we do not have which i think we could benefit from a at times.
british humour is more sophisticated than american humour imo
