" The only people who ever called me were my dad, my brother, assorted Vaders to tell me to come early or late to work (including Sean, but he always sounded grumpy that he had to call me, so it wasn’t as big a thrill as you’d think), Tammy to tell me to come early or late to tennis practice, and Frances. I glanced at the caller ID screen and clicked the phone on. “What’s up, Fanny?”
From the time Mom died until I was eleven, Frances the au pair had hung out in the background of my life. Once Sean overheard someone calling her Fanny, whch apparently is a nickname for Frances. We found this shocking. I mean, who has a nickname that’s a synonym for derriere? Who’s named Frances in the first place? So the boys started calling her Fanny the Nanny. Then, Booty the Babysitter. Then, Butt I Don’t Need a Governess. This had everything to do with the nickname Fanny and the fact that she tried not to get upset at being addressed in this undignified manner when she was trying to raise compassionate, responsible children. It had nothing to do with her having an outsized rumpus. Frances had a cute figure, if you could see it under all that hippie-wear. "
