What's in a name?

I've been thinking, and what set off this thinking was when I heard Annie the other day calling Olivia "Liver". Hummm, I thought, just how many nicknames does that girl answer too?
Here is a short list...

Olivia
Olivea
Livie
Livia
Liv
Olive
Baby-O
A-livia
Bavie
Bav (this one is my favorite, it started with Annie not being able to pronounce baby)

and the newest one
Liver

It has a nice ring to it I guess. Might just have to add that last one to my rotation.
