nightowl, I agree it really depends how cosmopolitan the area you live in is. I can only assume if you haven't stumbled across this not so new phenomonen of the Eastern European car wash, where you live is rural. I wouldn't be able to recognise the nuanced differences between the Eastern European languages, although Russian does have a very clear tone and there are lots of them in London. I agree with Petra these languages tend to be harsh sounding and lack the attractive lilt of romantic languages, such as French/Italian/Spanish. I did read that Romanian is different because it has evolved from Latin, maybe because Roman soldiers on retirement were given tranches of land in Dasha (modern day Romania). I live in South West London and I'd say our area has been awash with Eastern Europeans since the UK granted permission for free movement back in the noughties. When they first started arriving their languages stood out, not anymore though, they're everywhere now. My husband always chats to the guys where he goes for his car wash, even if they have a rudimentary command of English, where they originate from tends to be the topic of a conversation.
