I tell you what I want you to call me. It’s a shortened version of my full name. Don’t call me anything else, why would you? Don’t try my real name, you probably can’t pronounce it right, and I love my name and hate hearing it butchered.
I also call everyone else by the names they introduce themselves by. So if you say “Robert,” I’ll never call you bob or bobby or robby. I may, if we get friendly enough, affectionately refer to you as Rob, but even that’s rare.
My name is Elizabeth. My mother thought how cool it would be to have a name where you could just have all the nicknames you could imagine. I have always gone by Elizabeth. I correct people who call me anything else, with only a very few exceptions.
I call people how they introduce themselves to me. If a third person introduces someone to me using a nickname, especially diminutive like Bobby or Billy, I usually end up asking them later “Do you generally go by Billy or Bill?” just to make sure.
My son who went by Charlie (and still does in family and close friends) started introducing himself as Charles to new people around aged 7. “It’s my name, Mom.” I was more than happy to oblige.
Oh, yeah…people who call you the wrong name on purpose because they think it’s funny should burn in hell.
For the first 19 years of my life, I went by a nickname that’s based on my first name. I hated my first name because I shared it with a classmate who really irritated me.
Then I left home and started dating a guy who didn’t do nicknames, and I decided I liked my given name after all, and I’ve used that for 40-ish years now. At one point when I was in the Navy, I was known as Fred - a totally random moniker bestowed upon me by a goofy coworker. Once I left San Diego, Fred disappeared.
In general, I HATE when people try to stick me with a nickname. The aforementioned classmate tried calling me a dimunitive based on my last name - thankfully, it never caught on with anyone and she quit. I had a teacher who called my by the masculine version of my name. :rolleyes: And there have been several over the years who thought I should be called by the last syllable of my first name. Um, no.
However, I’m OK with the MMP crown calling me Moooooooommmm… 
My name doesn’t really have a shortened version. My family sometimes calls me by the first syllable. A lot of people mishear and call me a more common version, which is annoying but I can live with.
When I have to give my name to cashiers and such I give a short version of my middle name (Kitty for Katherine).
My sisters given name is Jessie. She has ocassionally run into people that try to get all formal (usually little old ladies) that insist on calling her Jessica because “they refuse to use a nickname”. Which of course completely ignores the fact that her name is not Jessica.
I hate my full first name.
The only time I’m ever addressed by my full first name is when I’m in a class at my CC and a professor calls me by it.
Otherwise, I’m always, ALWAYS addressed via the shortened version. Everybody (even those in my family) knows me by the nickname.
It’s better that way.
My given name is Michael. I usually go by Mike.
My given name tends to be primarily used by female relatives, especially if they’re upset with me (and, if really upset, they add the middle name: “MichaelJOHN!”) 
Short form, thanks. If you pull the full name out, I feel like I’m being given a time-out.
I actually get the opposite of being called by a nickname. They ask if my given name is a diminutive of a longer name. It isn’t. When I was a youngster, I actually hated my name because they didn’t make personalized bicycle license plates with my name. :rolleyes: It’s a little more common now.
“We need more ‘Bort’ license plates in the gift shop. I repeat: we are sold out of ‘Bort’ license plates.”
I voted “other” because I honestly don’t really care what you call me - I’ll respond to anything, even swearing, most of the time! It seems I’m in the minority here, though. Note that I certainly don’t assume everyone else feels the same way - if in doubt, I’ll ask someone how they prefer to be addressed and then try not to forget.
Other: I don’t mind.
My name is David, some call me David, others call me Dave, either is fine with me. My surname gets transformed into nicknames occasionally, and I don’t mind that either.
Please use either use my full first name or the shortened version I tell you. Do not use the much more common shortened version of my first name - I will not respond.
(e.g. Full name Allen. I will respond to Len, but not Al.) Not my name but gives you the idea.
My first name is Julie. When I was in the first grade, the teacher’s aide insisted on calling me Julia. When I corrected her, she told me that my real name MUST be Julia “because Julie is a just a shortened version of Julia.” And besides, she insisted, Julia is just such a pretty name! Bitch.
My mother, God rest her sainted soul, called me “Dewey.” I miss that one a lot.
To my friends, I’m Julie or Jules. To my best friend, I’m “Goose.” Don’t even remember how that one started.
I have absolutely no preference. My name is no secret here, so I get called “Peter,” “Pete,” “Petey,” “P-Paw,” and “Pawinski” (with either a “w” or “v” sound for the “w”) all interchangeably. I’m not possessive about my name. Usually, “Peter” is the default (obviously). “Pete” tends to be the nickname males give me, and “Petey” tends to the nickname females give to me, although my best childhood male friend calls me “Petey” as well. “Pawinski” is pretty much an exclusively male appellation for me, mostly from grammar and high-school friends, although a few of my adult friends have called me that, too. “P-Paw” is kind of a silly nickname a handful of friends and acquaintances use.
ETA: Oh, and in other languages, there’s Piotr (Polish, formal), Piotrek (Polish, diminutive), Piotruś (Polish, diminutive), Piotruśek (Polish, diminutive), Pietruśka (Polish, literally means “parsely,” sound-alike nickname), Peti (Hungarian), and Petike (Hungarian, diminutive.) The diminutives (except for Piotrek) tend to be used by females or family members.
Shoot, and the “Peti” should also read “nickname” after it, as Péter is the formal name.
A shortened version of my *middle *name, which is what I go by. On the other hand, pretty much every Doper I’ve met in real life calls me “Jack” face-to-face. I’m cool with that too.
Other: it’s not really a nickname as I chose it in adulthood, as it better represents my personal identity. It has nothing to do with my given name. In fact, I’d legally change it if it weren’t so damned expensive to do so. I have used my name exclusively for over a decade and consider it my real name; it’s how I introduce myself to people. I only use my legal name for legal documents.
Most people respect how I introduce myself. I had one (now ex-, as of many years ago) friend who would NOT let me introduce myself, ever (she would interrupt me if I tried), and never introduced me by the right name. She was insane and self-absorbed on many levels, though; this was only one manifestation of it.
I don’t think I’ll ever break my family of the habit of calling me by the old name (my friends who have known me by both are pretty good about it, though), so I pretty much just let that go. It does irritate me when family introduces me to new people by the old name, though. I get that they will never think of me as CurrentName, but for Pete’s sake, they could make an effort. I am not OldName. I haven’t been for many many years. It’s no secret. I never quite know how to respond – since they mean well, it seems a bit awkward/peevish to correct them, but then I get stuck with some guy I barely know constantly calling me by the wrong name. (If anyone has suggestions, I’m all ears.)
It’s not the rage of a thousand burning suns or anything, but it grates.
That being said, the only person who is regularly allowed to call me a nickname is my SO. I know he does it out of love.
+1 to the idea that people who call you a name because they think it’s funny are douchebags. I’ve gotten very good at freezing people out and saying, “My name is ____.” But these assholes just keep doing it and doing it.
Kaio, my family still calls me by my baby name, and introduces me to everyone through it. I hate it, but I realize they are never going to change.
