Mary Poppins when I'm teasing her about being such a spot-on good therapist.
Pollyanna when her seemingly unrealistic optimism gets on my nerves, haha.
Fairy Godmother when I feel blessed to have her in my life.
Oh, and Laverne and Shirley when I'm feeling chummy with her- she decided she'd be Laverne though! Oh well.

I am a brunette anyhow.
