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