oh... that sucks! Would anyone ever change their name except for the traditional changing of last names due to marriage?
My parents named me something not wildly crazy but still my whole life every single time I meet someone I have had to correct them and have this huge ordeal about how to pronounce it. People at school couldn't spell it properly and some people, no matter how many times I correct them would never get it right and/or forget. Heh, or I'd get the excuse, "ohhh well my cousin/daughter's friend/baby mama whatever pronounces it THIS way". (*thinks to self: so freaking what, this is how my name is pronounced)
Plus, I was extremely shy as a child too and wanted to change my name SO badly but my parents were like no. For a period of time when I was a teenager and went through depression, I just stopped correcting people all together and fumed whenever they said my name wrong, feeling like I had no real identity.
As an adult, I am much more bold and confident and will MAKE people say it correctly, but I'm pleasant about it. It's amazing when I meet another girl like me at school or in a store who spells AND pronounces it like me and we instantly bond like it's a secret sisterhood or something. Now, I would never, ever change it, because it's part of who I am.
I think having to be assertive about my name helped make me be more confident and I do feel like a unique (in a good way) person. However, I absolutely wouldn't do this to my daughter. I think it's downright cruel to give kids in America weird names (if you want to be "creative" use it as a middle name!) and I don't blame anyone a bit for wanting to change them. Tallulah is probably the best name out of her sisters, but I fully support it if she wants to change it.
