My first name is not uncommon, nor is it exactly common, it's only 5 letters long and in general fairly easy for most people to pronounce. I prefer to go by the three letter, 1 syllable long nickname. Easy, right?
I've gotten called Veronica, Betty, Carol, Rachel etc. And my first name doesn't start with any of those letters and they're way longer than what I use when answering the phone at work. And I've been told that I have one of those "generic Midwestern accents", even though I've never lived out there, but it's probably because I've been working in call centers for so long that I've worked to keep from having an accent. So it's not how I say things.
