So within the next few weeks, I'm getting this puppy right here!! Buttttt I don't know what to name her. I do know I want to name her something Billie related. I was thinking maybe Nova (Billie Bossa Nova) or maybe Halley (Halley's Comet) I could also do ilomilo, or ilo (or milo) but idk. Please help me pick a name!!!
