a llama in your sternum.

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