Purely by force of habit and not to annoy her, Jennifer gets called Jenny a lot. And she's let it be known that she cannot stand the name Jenny and corrects us each and every time someone does it.
I understand not wanting to be called a name you don't identify with, and we're all getting better at not calling her Jenny. However, there has not been one time that we have accidentally called her Jenny that she has failed to pounce on us and make a big deal about it, not just a simple "it's Jen" but a arm-flapping, huffy guilt trip. Is this unreasonable?
Occasionally, she will fail to respond or she will give an unexpected response until we rephrase it properly. "Jenny, can you pass me that file?". "No.". "...Jennifer, will you pass me that file?" "Sure!". Is this unreasonable?
EDIT: I certainly don't mean to suggest it's unreasonable for her to try to get us to call her the right name. Everyone at the job got me and a coworker's names backwards for the first few weeks and no doubt it was annoying. What I'm asking about is the means by which she's trying to get us to change.
