Cloud Movement

Our family enjoyed some outdoor time this evening, seeing as it was the first cool night of the season. When we returned from a walk, we spent some time in the back yard. I was pushing Po on the swing, and we were looking at the plane lights cut through the clouds in the sky. We were also observing stars. He said "hey, where did that star go?"

I told him, "it's still there. We just can't see it because the cloud moved and came between it and us."

"Oh," he replied, "I didn't realize that clouds migrate, too."
