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