I like my current username. Except sometimes people pronounce la belle like 'label', like the kind you stick to things. >.< I do feel a little bit weird about it though since when I starting using it, I was close to fluent in French, but I haven't spoken it in several years so I hardly understand anything now.
If anything, it's much better than the username I used to go by as an 11 year-old on the internet, which was Princess Giggles. I even got in trouble for using it instead of my real name for my e-mails to my school pen pals haha.
