Where is everyone from?

From Norway! I guess there's a big focus on fish. Especially where I live.
One thing I learnt recently that I guess is a bit interesting is that we norwegians, when we don't quite catch something what someone else said in a conversation, we don't answer with "can you say it again? I didn't hear what you said". Instead we answer with a simple "H?", like "huh?". For people not used with this i guess it would come off as quite rude, but in Norway it's so normal!
