Like my OH Mike. Born in London, moved to South Wales pre-school, then Scotland when he was about seven. His memories of having an English accent at his first school in Scotland weren't happy ones! He picked up the lingo quickly, but has reverted since moving away. We came to South Yorks in our early twenties. My connection to Dundee is stronger than his, he feels strangely at home in London, and his older brother moved back there as a young man. I now have no relatives left in Dundee, but his younger siblings all live there, as do most of their children/grandchildren.
Nice reminder of the Sidlaws!
