Mad as a hatter?My great-grandfather used to tell me, "Don't chase after rabbits because you'll only end up with a Wonderland in your head." I never quite understood his advice until one Easter, I was gardening with my best friend Alice. All of a sudden, we found an underground tunnel! It was mad and spooky sounds came from deep within. Alice saw something interesting inside, jumped in, and I never saw her again. Great-granddaddy was right!
