Ok, Zf. Cat :) If that makes you feel comfortable it costs me nothing to be considerate of your preference. See?
Now you have to remember that for every interaction with me. If you happen to call me sometime else, I’ll grit my teeth and have to correct you or if I’m an asshole, I’ll berate you about it, constantly. You will also have to refer to me as Zf. Cat to everyone you know, regardless of whether or not they know me, or are in my presence.
You should be asking yourself why you assume the person would react angrily instead of just politely correcting the pronunciation. If someone accidentally mispronounces my name I gently correct them, while smiling, and I have never once been offended or take it personally. You also assume it is a heavy burden on others to simply call people what they’d like to be called. When it is not. Being angry over this is not a healthy attitude. It’s simple manners to be considerate of others and that is precisely what the person is asking for, nothing more.
If you have to correct someone about your name/title every single time it gets pretty damn annoying. I met a girl years ago whose name was spelled Remy but pronounced Ray-me she said “I hate my parents for it” (I doubt she actually hated her parents, but hated the fact that they gave her a “bad” name).
