Well, obviously, let start with the locals!
I want to point out that my experience and my observations focus on the welsh population as I mainly lived in Wales.
I have been greatly surprised by the Welsh people. And every British in general. As I grew up in Paris, the human being always seemed to me embittered and devoid of interest!
However, in the UK, I got passionate about people. Their open-mindeness, their generosity, their politeness… Brought me a haven of peace!
