I would say that most of the time I'm a Bella (with a little less acne yikes), at work I'm a Caroline in full peppy customer service mode, and a Willow if I'm getting dolled up for an event.
I love the Elise/Eliza connection. It makes even more sense since Eliza always hung out with Darwin the chimpanzee.
For myself, I think I probably look like Bettina the mouse. I have brown hair and eyes and I've always thought I looked plain and mousy. I don't really have any stand-out features. I also associate myself with her normal personality and our names share some similarities.
