I didn't think about that, but English isn't my first language and there are studies out there that say that you think different in languages that aren't your mothertongue. That being said, my English meetings with my British and my Eastern European colleagues still feel a lot more normal than meetings with American colleagues
It is not my mother tongue either but the British, or at least the English, are famous for being phlegmatic where as US-Americans are famous for being enthousiastic. Of course, it impact the way they speak.
But we'll need a british lemming and an american one to cheek on that.
You are right. I so full of my (american) english corrector telling me I don't know how to write "neighbour" and "colour" that I don't trust him to spot abusive use of "ou".
