I was born in South London, in those days it was "North Surrey"
My future wife and I moved into a flat in Soho when we were nineteen.
I changed jobs at the age of 25 in 1965 and we and our three kids, living in North London by then moved to south Manchester.
We're still here.
There were and still are, a lot of ex-Londoners who live in this area.
The first thing I noticed was that Northerners speak more slowly than Londoners.
Then there's the accents, as in London there are regional ones. I could understand them but not so all, mine.
In our first week in Manchester, my wife asked me to go into a big department store and buy her some buttons.
I asked an assistant. "Do you sell buttons?"
"Paper patterns?"
"No buttons, like these," pointing at one on my shirt.
"Oh! You mean bootons!"
Yes, people were more friendly, you were often addressed as "Love" or "Chuck."
It was also evident that many people you met, lived and worked not far from where they were born.
Accents are amusing. Our youngest son's ex wife came from a posh area of West Horton, a suburb of Bolton.
When they moved into a house, she decided they needed another power socket in the kitchen. He told her he could run another from an existing one.
She replied "Ooo" You're picking up the accent!"
To which he replied "No I'm not, I said I could run a spur, not a spare."
As for regional accents. In a converstion with a woman who worked for me, she told me that she originally came from London many years before.
I said, "I can tell, you come from Peckham." She was astonished that I was correct.
Lots of people are unaware of their accents.
