Wise advice

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