As a kid, I was just kind of meh on it. I was more or less okay with my nickname, "Charlie." That name didn't bother me so much. However, I have always NEVER been a fan of what my actual legal birth name was, "Charles." It wasn't until I was an adult that I started hating my nickname too.
In French class in 2nd grade, we had to find French names for ourselves. And I was really disappointed that, while other kids got to pick different names because their names weren't on the list of French names, the name "Charles" was on the list. I refused to go by "Charles," so I actually opted to go by "Claus" instead.
I remember a specific incident in music class in 3rd grade where we were clapping out the syllables in our names with "ta"s and "ti-ti"s. In my own head, I had a four-syllable "ta ta ta ta" pattern planned out, and I liked how even it sounded. But when the music teacher got around to me, she messed it up by using my legal name, and it became "ta (rest) ta ta," and I whined about how that didn't sound right.
In middle school, I remember having several episodes where all of a sudden I'd be looking at my name on paper, and all of a sudden the name "Charlie" just started looking completely weird. (I don't know how many people have these episodes, where all of a sudden when you think of how the letters in a particular word are spelled, and how they all somehow strangely come together to mean a certain thing, it just all seems completely ridiculous for a few seconds? I had a lot of those episodes with my name. Again, though, it's not like I disliked my name, it's just that I didn't ever really like it either, it was just the name I was given.)
Then, as an adult, I slowly started hating my nickname too. Because dear God, the sheer amount of references that people started making with the name "Charlie"... they teased me about Charlie Brown, Charlie and the Chocolate Factory, Charlie the Tuna (sometimes I seriously think people's favorite passtime is saying "Sorry, Charlie,") Choo-Choo Charlie from the old Good 'N Plenty commercial, I got TORTURED by Youtube's "Charlie the Unicorn" video ("Chaaaaarlie.... come to candy mountain, Chaaaaaarlie!" URGH... >.<), not to mention another Youtube video "Charlie Bit My Finger," and Charlie's Angels to go along with it. Pop culture just was not kind to my name. I pity anyone with that freaking name...
And I wasn't willing to start going by "Charles," because, I don't know, that name felt too "masculine" and "grown-up" somehow. I didn't want to be powerful or official or kingly or grown-up, I wanted a name that still ended in the feminine dimunuitive "ie." So independent of gender dysphoria, I really started hating my name.
By the time I legally changed my name, I was really glad to be rid of it. Now the only references that people make in regards to me are "Sweet Caroline" by Neil Diamond, another obscure 50s song called "Carrie," and the 1976 horror movie "Carrie." I can handle all of those references. They're all good references to things that I actually like, rather than just constant, constant, constant annoyances. And I'll admit, I still smile like crazy every time I see my new first and middle name, "Caroline Elizabeth." I LOVE LOVE LOVE that combination. It's so pretty!
