The Phases of the Moon - by Sam

Sam pointed out the moon to me last week, explaining that it was a half moon.

After a minute, during which time I assume he was pondering how the moon goes through the different phases, he said: "Mom, I think maybe a rocket man flies up to the moon with a knife and cuts it in half."

I tried explaining how it actually happens with the moon reflecting the light of the sun and the Earth blocking the light.  Sam came back with, "But how does the moon get cut in half??"

I think we'll stick with the rocket man theory for now.
