I was born in Scotland but spent time between Scotland and England, and we moved around within the UK each year or so. I don’t have a regional accent but somehow sound like I am from London which is where people tend to guess.
I often get asked where I’m from “originally” by people trying to make conversation and they make references to having gone to London and the topic doesn’t interest me. I need a way to move the conversation on.
Also I am not imagining this I have been spoken to like absolute rubbish by some (not all) locals just because they think I’m English.
Some people even assume I am loaded (I’m not) because of my accent and ask how I paid for something or how much money I have or what I work as.
