I was driving the other day with mom, grandmother, and youngest nephew Andrew, age 4. Seemingly out of the blue, Andrew asked my mom who Einstein was. I was not a little impressed. This from a little kid who is only exposed to cartoons and videos, as far as I know.
Mom tried to simply explain who Einstein was, with me trying to help. Basically, we told him he was a very smart man, blahblahblah. After a moment of silence, Andrew asked "Is he like the Hulk?" which brought another moment of silence from us. Finally I said "No, the Hulk is just pretend and Einstein is a real man." After a beat, my mom asked Andrew "Wait. Are you talking about Frankenstein?"
Andrew: "Yeah".
I laughed til I cried while simultaneously driving down the highway.
