Oh, I've been around in the world, as Macmillan would have said. I've never been to the US but I've been to Australia and Hong Kong. Too long ago and too briefly to use for this decision though. The longest I've been outside of Sweden, consecutively, is 6 weeks in England. So I've never really lived permanently abroad. But I've been too a fair share of countries.
It would be for the fall term (Sweden doesn't have a summer term).
And while I appreciate the sentiment, being from Sweden doesn't mean I've never experienced warm weather.
I've spent a summer month in China, after all.
