Across the Pond

[RogerDuke]

I'm friends with a family from England who have been here over 25 years. 10 kids in the family. The parents have accents but you can tell they've been here awhile. Only the 2 oldest kids have accents. The oldest hasn't lost it a bit. Sounds much more British than her parents.

British English often comes with subtext and inferred meanings whereas American English tends to be more direct. Here's a video by an American who's been living in the UK for a while. In it, she describes some of the phrases that initially confused her.
