Well, what are nicknames for, after all?
At first, I went by "Emily-Emma" from Preschool (or maybe Pre-K?) through Kindergarten because I liked the name "Emily-Elizabeth" from Clifford. Then, I began watching Dragon Tales, where there was a character named "Emmy", and I became "Emmie" until 8th grade, where I switched schools and learned there was a ninth grader with the exact same nickname, spelling and all (her real name was Amelia, though, which isn't close to mine).
I have had other favorites, though. "Rachelle", "Julia" (which could've been my middle name, actually), "Mitsuki" (sadly nabbed from Full Moon o Sagashite ;;), "Lucia" (which is what I use on here nowadays), etc.
Personally, I'm more up for changing my last name. I could've done that when my mom got remarried, but Idk why I chose not to. Anyways, I'm thinking of changing that to "Vaughn" because it sounds cooler than a synonym for "rear end" with a consonant added at the end. I'll lose my "ER" ("Emergency Room" for those who don't know abbreviations well enough) initials, but then I'll be "EV" (which sounds like "Eevee" when said, or for those who love taking advantage of Pokemon game mechanics, it stands for "Effort Value").
But yeah. My parents named me after someone they really cared for, and not just some random celebrity or TV character. And for that, I'm proud to have my name.
