Cave Paintings

After school I help with bus duty. Some of the kindergartners line up next to the building to wait for their bus. I normally go and talk to them while they wait. Friday, one of the boys was simply being a five year old. He was practicing his balance by lifting one leg off of the ground and freezing....then he would put the leg down. Next he would lift the other leg and freeze. In combination with this, he would also contort his arms as well and freeze. I think you get the picture. Anyway, the following is his one sided conversation with me.

Student: "Miss Felix, you know what?"

Me: "What?"

Student: "If there was a tiger in front of me right now...he wouldn't be able to see me."

Me: "Yes?!?" (I was thinking his response would relate to his ability to "freeze")

Student: "Because I look just like a cave painting. The tiger would think my body was painted
on the wall"

Me: ".....(no response)"

I have no idea where a five year old would learn about cave paintings.....
