Know it all

When I brought my 4 year old granddaughter to school this morning, she noticed one of her friends along the way. "Look it´s Keanu," she said. "And that´s her grandma. Do you know her?" I said: "Yes, I've seen her before."
"No," she said. "I mean do you know her name?"
"Oh, I see. No, I don't."
"I know your name," she said looking up to me.
"You do?" I said.
"Well, of course... your name is Grandpa!"
