I have a confession to make. Like most people, I talk to myself. Out loud. But I take it one awesome step further. I like to talk to myself in a British accent. It kinda makes me feel smarter and more suave.
I love accents of all kinds. British, Irish, Scottish, Austrailian. . . . it doesn’t matter. I like ’em all. There’s just something about an accent that’s not American that appeals to me, probably because I don’t hear it every day.
I’m not saying I’m particularly good at accents. When I talk to myself in my British accent, it sounds like I’m from all over the country. One moment I might sound gentrified and upper-class, one moment I might sound Cockney. It just depends on what movie I’ve been watching lately.
One day, I will make it to England and Scotland and Ireland. I hope to visit some of the villages and smaller towns and take in the scenery and have bangers and mash and fish and chips and (if I’m brave enough) even haggis. But I’ll stick to my own American accent, so no one gets embarrased.
I wonder sometimes if someone from England ever walks around talking to him (or her)self with an American accent, although I can’t imagine why. What would be the fun in that?

As an American who spent 3 years in England, I can tell you:
1) In and around London, American accents aren’t special.
2) Further away from London, American accents are sometimes seen as “cool” by the younger generations (American = Hollywood)
3) American personalities stick out there far more than their accents (we’re all showmen)
4) You will stick out too (though no one’s likely to tell you so), but you should most definitely visit!!! England, Scotland, and Ireland are all amazing places with rich history. They will not be what you expect!
I do this all the time! I’m hoping one day it’ll be super good and then become habit so I can convince people I’m british
