Ok this is crazy, but I have been laughed at because I pronounced this name as it is. Here's the scenario, I have a female co-worker and evry one in office calls her "FIFI", including me of course. One day I was sending out an email to everyone but I couldn't find her name in the database…So at the end of my mail, I wrote in:
"Pls pass this along to FIFI, as I can't find her email add"
I got tons of reply immediately after that asking "WHO IS FIFI"?
So I went to this "FIFI" and told every one, This is FIFI!!!
Man I still remember the smirk on every one's face when I said that, and immediately one of them corrected me saying "It's spelled V-I-V-I". To my shock I blurted out V-I-V-I, it's pronounced as VIVI!, then everyone started laughing and still insisting it's FIFI!!!
Naturally I didn't give up, so the next day I brought with me an episode of OP, with Princess Vivi of course, and let some of my co-workers watch. My point of course, was for them to hear Vivi's name pronounced properly(It's in Japanese, but with English translation). So when Vivi's name was called, I immediately said "See it's pronounced as VIVI". Of course they didn't accept it, saying it's "Japanese, so it doesn't count".
Finally my last resort was to go to an online dictionary and look for a word very close to vivi's spelling. I found VIVID, and again let others hear how it's pronounced(the online dictionary has audio pronunciation). Still they didn't accept and still insisting I was wrong, and they were right with the FIFI thing.
I gave up after that and to this day I call that girl FIFI. I'm not a natural born English speaker, but I can communicate using the language. I work at an American MNC based somewhere in Asia, where people insist their first language is English, but....ahh nevermind. I'm an expat and I use American English, as the people over here keeps on insisting they use "British", although to be honest...ahhh again nevermind. So how exactly is Vivi pronounced in your location?
