Oh I'm with you there!
When I first met my future MIL, and opened my mouth, and a Yorkshire accent came out followed by 'what do you do' etc and I was only a 'nurse' not a lawyer or doctor, well, that was that!!
Somerset - my neighbouring county is where The Wurzels come from, and there is an accent, and very country yokel it is, so 'now't special there' as my countrymen would say. You've that or Jacob Rees-Mogg, take your pick!
In October 2021 I moved my mum down to be near me as it was getting so that she needed a bit of help and I was 3-4 hours away and was getting so that I couldn't safely drive that far. She has moved to a village about 15 minutes away - a nice pretty village, but they obviously don't sound like she does, having lived in Yorkshire for 85 years, and she has found it quite difficult to integrate really as everyone appears to her to have a lot of money and be 'posh', they obviously aren't all made of money, or posh, but to her they sound as if they are! She has just gained a new neighbour, and they seem to be getting on, so fingers crossed she can actually find a friend, rather than lots of acquaintances ....
To be honest she doesn't sound lie a very peasant individual all round, but I suspect she knows that she isn't as well educated etc and maybe feels a bit intimidated by it and that is why she is doing it?
