My great-grandfather used to tell me, "Don't chase after dust bunnies because you'll only end up with a meerkat in your belly button." I never quite understood his advice until one St. Patrick's Day , I was gardening with my best friend Vanessa. All of a sudden, we found an underground tunnel! It was warty and spooky sounds came from deep within. Vanessa saw something interesting inside, jumped in, and I never saw her again. Great-granddaddy was right!
