James drove himself and his wife home and parked his car in their driveway. The second he stepped out of the car and shut the door behind him, he heard the strange sound. He quickly turned to his wife with a deep frown between his eyebrows, “Do you hear that?” He asked. She nodded as she responded, “Yeah, what is that?”. It was a sound that neither of them had ever heard before. James grew curious and decided it was best to investigate the odd sound.
