CIA Instincts
This is probably something everyone will attribute to wear and tear. No one would even give this a second thought. However, one person took notice of this door handle, and decided the scratches on the left handle were the result of people’s wedding rings on their left hands.
This person is a true detective. He just walks around detecting things. Solving riddles. Doing this thing. Some people are perceptive like that, and they take notice of everything around them. Perhaps he’s some kind of a genius. Either way, we’d hate to think his talent is wasted on small, insignificant things such as this random door handle.
