Sammy learned about rainbows this week. If you ask him what a rainbow is he'll tell you that it's God's promise to the world that He will never flood the entire earth again. He will also tell you that water drops are tiny prisms that reflect light from the sun that makes the colors of the rainbow. I wasn't surprised that he remembered all of that, but I was surprised that he remembered the color order on the rainbow when I saw his painting. What a memory!
