My 4 year old keeps asking people this question.
"Do you know everything?"
He asks it with the innocence of someone who genuinely wants to know. It's like he's searching for someone who has the meaning of life or something.
Today, he's asked the UPS man, the house painter across the street and a cop.
He keeps asking Dave and I, also. We tell him the truth, that we don't know everything and nobody does. We tell him if anyone tells him they do know everything, they are lying. I think he believes us but only a little. Because he's still searching for that omniscient person.
Still learning, Ruth!
