I was thinking of something funny - I didn't understand 'fancy dress' when I moved over here as being a costume party kind of thing! I thought it meant I had to wear something like what you might wear to a wedding, semi-formal, etc. Lol! I still get laughs from DH when I ask if I have to dress up 'fancy' for something, because it so means something completely different to me!
The 'careered' thing - this was the first I've heard of that! Oh, on a similar note, I've heard people here say that someone 'cut me up' in traffic, rather than they 'cut me off'. (I think that's what they say or is it some other variation?) That makes me laugh too!
