My mother named me Kimberly Ann. Presumably because she liked that name. However, I was opinionated and contrarian even as a child. This is shocking to everyone who knows me now, I am sure.
When I was a toddler, I would ball up my fists and declare, "I am Pimmie Annie Fota!" A drama queen was born.
As origin stories, go, this one is weak. But at least you know where the name came from.
