What I'm finding interesting is moving back to Australia after living away for almost 20 years, most of that time in the UK.
Very first thing I noticed at work was everyone is much more positive and laid back. In the UK someone calling to say their computer wasn't working was worst thing in the world, Australia its an inconvenience but understand these things happen.
Australia is more informal which my wife doesn't really like. both is dress code and talking to people authority e.g. calling your doctor by his first name.
I never noticed it till moving away but Australia does feel so far away from anywhere else.
now as a foreigner in the UK.
Even in London people are friendly, Had plenty of conversations with random people in the pub, train station, etc you just have to catch them when they are idle and not in the middle of something which may be as simple as reading a book.
Yes it's always raining but who cares? mostly it's just light drizzle and doesn't stop you from whatever your doing and you do really appreciate the warm sunny days that do happen.
Also agree UK's beauty is outside London which isn't rally that far (we lived in Essex surrounded with farms yet only an hr from the city)
Lived in Genoa Italy for a month and found people friendly and helpful which is lucky as nothing works properly, People were more stuck in their ways vs London and even a cloudy day was enough to cancel weekend plans.
Lived in Kelowna Canada for a ski season so probably the least "authentic" but found the locals the most friendly of anywhere but also the most demanding (in a nice way) but where as in other countries something goes wrong your typically expected to fix it yourself. Here it was common to call and have the hotel/etc to sort it. I suspect this is due to the tipping culture and people more willing to help then the other countries.
