"Lucy in the Sky with Diamonds"

Driving home today after a rainstorm, the sunset was behind the clouds. The result was that the clouds were illuminated and washed with color. It was quite spectacular.  We were listening to a Beatles cd and Sam and I were commenting on the sky.  Suddenly he exclaimed, "Mom!  I know why the sky is like that and the clouds are lit up!  The man is singing "skyyyy...." very loud, so the sun listens to him and Lucy!"
