I and my brother were frightened by thunder at a very early age. My mom chided us saying it was just a silly black cloud. That started it. We didn't have a boogey man in our household, we had the "Silly Black Cloud" hiding in closets waiting to devour us. He'd come out during thunderstorms and search for us. I finally read a science book (I was 11 years old!) that described what thunder really was. No more Silly Black Cloud, may he rest in peace.
