..but I never known the "other" nationality from my perspective - so for me, living in Scotland wasn't living overseas, it was living at home.
I left there when I was three, my parents had no pride in the place, but they loved Scotland. As it happened, my mum happened to have been born in Scotland - by pure chance, as her father was working here during the war. It meant that it was easier for her to bring the family in on "her" passport as it were. (My dad could have claimed a British passport but it would have been long winded as his mother was half German, half English). I then became naturalised British as soon as soon as I could (or rather, my parents did it on my behalf).
Now, when we emigrated to New Zealand in my teens, that was living "overseas", even though it was planned to be a permanent move. It never felt like "home" to my parents, so we came back to Scotland. Politics played a part in that decision: quite apart from the parochialism that they felt (they made the mistake of not going to one of the big relatively speaking cities), the last straw was a general election being fought and won on the basis that the government would sent the All Blacks to play in South Africa with its blessing . They didn't miss their old country - they missed Scotland.
I suppose I'm also used to having family all around the world - and of many different nationalities. Amongst my grandparents, aunts, uncles, cousins and 2nd cousins (blood related) I have: Danish, German, English, Australian and South African. I don't love them any less because I am Scottish. :)
