I was about to post "...maybe because I live in south america ... but Firefly is a pretty weird name ...." xD
You people make it too complicated ... with great naming powers comes great responsability xD
I just add a letter to my id name (girl version) because my name "if I was born a girl" is ... my sister's name =P
I can't handle the female version of my male name, I feel like I need to get as far away from it as possible. Changing my entire name, though I dunno what to pick for a middle name yet.
