Living in England, I have found these pages fascinating because some of the irritations are just the same here! One that's annoying me is people writing "should of" instead of "should have".
I was brought up in the Midlands (Nottingham) and had to get used to my husband and his family (brought up on the south coast in Brighton) saying "Somewhen" which I had never heard before - I heard myself saying it the other day because it does actually have a use!
I lived more than 30 years in Edinburgh, Scotland and still use words like "swithering" which is what you do when you can't make up your mind, or "peely wally" which is when you look pale and unwell.
I struggled with the local dialect in Bristol when we first moved here, especially when for instance giving someone my address they would say "Where's that to then?" - meaning "where in Bristol is it?"
It all adds to life's rich tapestry!
