I dont know about this

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