Clouds

Where do clouds come from? There were no clouds in the sky last night....I know because I wished upon a star. The moon was bright and shiny and the man in the moon smiled at me . This morning it is cloudy and drizzly....where did all this grey stuff in the sky come from?? And, how can I send it back where it belongs? Who do I write to to complain?? I want to go right to the top to the Chief Cloud Maker...do you know his/her address??
