When I was a kid, around 10 or 11, I loved fantasy novels, especially The Lord of the Rings and The Chronicles of Narnia. I read these books over and over, and with my friend Michael would act out the various scenes of the books. We would run around the yard with toy swords and trash can lids for shields, battling monsters until it got too dark to play any longer. One day we were pretending we were wizards, casting spells and dispensing vague wisdom to our imaginary comrades. As part of our costumes we made hoods out of pillow cases, and were blithely going about our business when my dad came home.
