Hahaha, I don’t know why this made me laugh, but it did.
I went to university in the UK, ironically studying America (people always get a kick out of that). And yeah, people would often try and imitate my accent and would usually end up sounding either extremely and stereotypically southern (I’m from the northeast, so that was a fail), or like an effeminate pirate with way too much emphasis on the R sounds. I was told that I still sounded very American to them most times, but I did pick up the intonation, especially when asking questions, and a lot of the vocab and spelling. I’ve been back in the US for about 6 months now and I think I’ve dropped most of that unless I’m talking to an English friend, but occasionally, especially in the first few months, people would tell me that I said something I just said “with an accent,” so go figure.
