Mummy knows Everyone

Incident 1
AN: "Mummy, you know this guy, Einstein?"
Me: "Yup. Why?"
AN: "He's a singer. And he's very smart."
Me: "Errrr.....then I don't know this Einstein. The one I know of, Albert Einstein, is an inventor. He discovered light."
AN started thinking and corrected herself: "Oh yes mum! You are right! You are so smart! Did we have the same teacher?"

Incident 2
AN: "Mum, do you know Florence?"
Me: "Nightingale? Florence Nightingale, the nurse?"
AN: "Yes! Wow, mum! How come you know everybody?"
