My name is [name]Jessica[/name] and all my life people have called me [name]Jess[/name] or [name]Jessie[/name] from first meeting me. I’ll introduce myself as [name]Jessica[/name] but they’ll still call me [name]Jess[/name] or [name]Jessie[/name] just because I have that kind of nick-nameable-name I guess. I don’t mind at all, it actually feels like a kind of endearment when someone shortens my name, I just think it’s interesting they take the initiative without any prompting. [name]Do[/name] you ever get called nicknames by strangers or teachers you’ve just met etc? And do you mind?
My name is [name]Candice[/name], the only real nn you can use is [name]Candy[/name] and most people (including myself) avoid it because its a stripper name
I usually get called [name]Rachel[/name] but once in a while a random person will call me Rach. It usually throws me off but it doesn’t bother me :).
My name is [name]Toni[/name] and I get called Toe or Tone all the time. It just happens. The only one that really drove me crazy was a roommate that insisted on calling me Tone-tone.
My name is [name]Alexis[/name], and generally if I introduce myself to people with my full name, they call me by it. I go by [name]Lexi[/name] with my friends and family, and some people shorten it even further to [name]Lex[/name]… But I used to make EVERYONE call me [name]Alexis[/name], and some of my older friends still do, so the new people I meet are very confused about what my actual name is, because everyone calls me something different. I don’t mind at all, but it makes things confusing occasionally.
@nercomi: My sister is [name]Candice[/name] and I often call her Cando 
My name is Vassiliki and this is automatically shorted to Vasso which I hate. When I introduced myself to Greek people they always shorted to Vasso which frustrated me because I usually introduced myself as Vassiliki or [name]Bellerose[/name] but they keep saying "so you are a Vasso, right ? " it just get annoyed!
some people have a hard time pronouncing my name, [name]Lorelei[/name], so they call me [name]Lori[/name]. I don’t like [name]Lori[/name] or [name]Laura[/name] so I tell them to call me [name]Lola[/name].
I’m also a [name]Jessica[/name] who almost 99% of the time gets called [name]Jess[/name]. Different then you though, I almost never get called [name]Jessie[/name] (now, as a youngster I always did). I think that’s because most people find the name [name]Jessie[/name] on the more childish side, so they don’t naturally call me a kid-ish nickname (Kind of like how you probably wouldn’t call an adult aged [name]Daniel[/name] “[name]Danny[/name]” upon first meeting him)
The only time it bothers me is when I introduce myself as [name]Jessica[/name]-nickname-[name]Jessa[/name] and people call me [name]Jess[/name]. It’s like, I’m already TELLING you my nickname, don’t give me another one!
My name is [name]Emily[/name]. Never gets shortened automatically.
I’m [name]Margaret[/name], and yes people shorten it automatically (always to [name]Maggie[/name]) and if I’m being honest, it does bother me.
[name]Margaret[/name] is my formal/official name, whereas [name]Maggie[/name] is my “personal” name, one that I invite people to call me.
If I haven’t invited someone to use [name]Maggie[/name], I do expect them to use [name]Margaret[/name], I think it’s rude to automatically shorten someone’s name.
Perhaps I’m just very sensitive though.
NB: I’m happy for everyone on NB to call me [name]Maggie[/name]! 
I am a [name]Jennifer[/name] who is always getting called [name]Jen[/name]. Occasionally, I will get called [name]Jenny[/name], but I make a point to let them know I prefer not to be called by that nickname. I don’t mind being called [name]Jen[/name], but it is usually something that my family and friends call me. When a stranger or someone I am not very close with calls me [name]Jen[/name] I kind of am taken off guard.
It does happen to me, but only rarely. When I was a kid I went by [name]Margaret[/name], and would occasionally get Marg or [name]Margie[/name]. I loathe both of these nicknames, but usually failing to respond did the trick. Now I have the opposite problem as @maggiemary, in that sometimes I introduce myself as [name]Maggie[/name] and they will call me [name]Margaret[/name]. I wouldn’t say it bothers me, but I think it’s kind of weird. Unless I’ve introduced myself as “most high queen” or something equally ridiculous, I expect you to call me by the name I introduced myself as! But like I said, this happens very rarely.
There are a couple of people who automatically shorten my name to [name]Mags[/name], but they tend to be the kind of people who shorten everyone’s name automatically, and I think it’s kind of cute.
I think I have a very “nickname-able name” ([name]Kathryn[/name]), but I have never had this problem. People always ask “do you go by [name]Kathryn[/name] or something else?” or “does anyone ever call you _____ ([name]Kathy[/name], [name]Katie[/name], [name]Kat[/name], [name]Kitty[/name], etc.)?” There were times when I was a kid that people got it wrong (the [name]Sunday[/name] school teacher overheard my uncle calling me “Kath” and thought I went by [name]Kathy[/name] “just like her”, so I felt bad correcting her; a French teacher called me [name]Kathy[/name] and the other [name]Catherine[/name] (who goes by [name]Cathy[/name]) [name]Catherine[/name] for an entire semester because she just couldn’t keep it straight), but it was always unintentional.
I totally dislike when I introduce myself and people then respond with a nickname. I smile and say “oh, only my mother can call me that. My name is…” If someone says “what is your name” and you give an answer, why would they then say something else? I don’t get it.
My name is [name]Catherine[/name], and when I introduce myself, people often ask me if that’s actually what I go by. They sometimes seem surprised and press further, asking whether anyone ever calls me [name]Kate[/name] or [name]Katie[/name] or whatever. When I just smile and say no, that I’m always just called [name]Catherine[/name], that’s usually the end of it.
I did have one boss who unilaterally decided to call me “[name]Cat[/name]” because [name]Catherine[/name] was “too long and too hard to spell.” I thought it was kind of funny, so I just went with it. I’m 31, though, and that has only happened once.
My name is very short ([name]Leah[/name]), so I’ve never really gotten any nicknames, which is actually one of the only things I dislike about my name, as all of my siblings have nicknames except for me. The girls on my soccer team in high school kind of gave me a nickname, but it was based on my last name. Other than that, the only thing people have (kiddingly) called me is [name]Lee[/name]-[name]Lee[/name], which is horrible.
I’m [name]Kate[/name], and often people will go straight to [name]Katie[/name]. I don’t like it because it feels a little too familiar/patronising for a stranger to call me that since it’s actually longer than my real name. Has that every happened to anyone?
My name has been shortened down to [name]Zee[/name], [name]Zel[/name], [name]Zella[/name], [name]Ella[/name], [name]Elly[/name], Eija and Elja by friends since I started school. I have always been the one to give my friends nicknames, so I’ve never really cared that my own name has been shortened down so much. My sister is called [name]Isabella[/name] and she has always gone by [name]Bella[/name], she barely responds to [name]Isabella[/name].
I’m [name]Catelin[/name] but I’ve been called [name]Cate[/name] since kindergarten so I guess yeah. I introduce myself as [name]Cate[/name] and only a select few people in my grade actually know my name is [name]Catelin[/name].
Though it is misspelled as [name]Kate[/name] a LOT, which is equally as annoying.
