I never had any accent at all until I moved away from home and discovered that nobody talked like me.
Took Zero Alpha to my Co Durham homeland a decade ago. In Sainsbury's she discovered she actually had to keep an eye on me, not follow the accent, cos they all talked like me. Even the woman who told her five year old nipper he couldn't have any sweets, "Cos yer've just had yer dinner, man." Dinner being lunch in durham, and "man" meaning absolutely nothing, being just a noise word on the end of a sentence.
Zero Alpha watches Emmerdale. I was dead chuffed when a character said, "You cannit do that, man, woman." She now understands that the construct, "man, woman, man" on the end of a sentence actually makes sense, adding the noise-word "man" to the bulk of the sentence, then again after the vocative "woman".
