It was really foggy this morning on the way to school and the boys were asking how the fog got there. I told them that its like the clouds in the sky. But just like the sun has to go to sleep, the clouds were tired and still taking a nap. Once they woke up they would fly back up into the sky. They really liked my explanation and I myself was pretty impressed with my own imagination. Who wants to know the scientific explanation when you can make it a lot more fun....science can come later!
