It is difficult to live in a new place, you don't really feel integrated even though you have friends, speak the language, go to events, pay your taxes, and get the jokes, you will always be the dane and a foreigner.
A thing I noticed when I was away is how stupid and mundane Danish everyday local politics look, and the same with the news cycle. I think it is refreshing and healthy perspective, and I would encourage everyone to go to another country just to get out of their bubble. And also to get some ammunition against people that keep spouting "If I moved to another country, I would assimilate".
When I returned I had adjusted to British service levels, and how fast it is. I was used to get a coffee within minutes of ordering, and when I went to a store and looked a little out of place, I would instantly get help. I got to observe my fellow Danes as a tourist, and oh boy, I now understand why they all seem to think we are rude, and don't really care at all!
But the most odd thing about being back home is that I don't really feel at home, my thoughts and language is some sort of strange danish/british amalgamation, and I feel like a foreigner, even though I bike the streets of my childhood, say hi to people I went to school with, and walk the forests and beaches I was going on adventures in as a child.
