I spent most of my adult life in North London and moved to the Pacific Northwest nearly 7 years ago so naturally pretty much everyone I work with is American. Sometimes I say something that denotes me as British, calling elevators lifts, or saying, 'I can't be faffed' to do something and we all have a good laugh, fair enough. However, I have one colleague who keeps commenting on it and it's starting to get to me.
For example, as part of a work committee, I had to do an 'icebreaker' activity for our team, and he sent a Teams message commenting that he was surprised at this as I was British. Afterwards he sent a message saying I'd done well despite being British and referring to me as a 'limey', he then went on to explain the term and tell me about his interest in British Naval History!
I messaged back saying I knew the term as my brother had been bullied with it when we were kids, commenting that 'kids can be so xenophobic', thinking that would be a big enough hint. But, no, he came back saying 'he came by it honestly' as his great grandmother came from X place in Britain!
I'm starting to feel weirdly 'othered' by this, am I being oversensitive?
YABU: you're being oversensitive, just let it slide
YANBU: that's annoying, address it directly
