A sign from God? How 'bout a sign from the Devil?
When I was in 5th grade, I wanted to develop my 'psychic' powers. I tried to move my pen with my mind and I was staring at it for minutes. I was concentrating sooo hard, focusing mentally on where I wanted the pen to move looking, concentrating, looking..... BAM!
The pen pops-up! I was freaked out! Did I really have psychic powers? Was it true? Could I also develop mind reading powers? I realized something I hadn't noticed before. My pen was on top of my notebook. The notebook was slightly indented downwards. It was the notebook that did the popping-up.
What a disappointment. And yet, that's how detectives solve crimes. Through the laws of physics and nature. In this case, it was mere coincidence and it makes for a good anecdote.
