Im aware of the whole “zee” vs “zed” thing. i actually say “zed” as well. I think mainly in the US people say “zee” and “dubya” for the letter W. At one point, I won a radio show contest and when I was spelling out my address, I said “double you” for W, and they asked me if I wanted to work for them. I asked them if they needed people that bad and they said “No. You actually said double you, using two separate words instead of dubya”, I’d have taken the job too, but I had a job at the time. In Japan, they say “zed” as well. We actually speak american(i do as well) in the US, the rest of the world speaks english. I’m confirming this again and again because we have friends visiting and they keep telling me about how people speak here. All I can say is “I know, I know”. haha
