An Experience at Work

It was one afternoon. Every colleague had to take turns cleaning a machine. And that day, it was my turn. There was a colleague working on something else near me. Next to him was an electric fan. I heard a sound like the switch of an electric fan being turned on. When I looked up, the fan suddenly started spinning. The colleague sitting next to it was startled on the spot. Because the fan was far enough that you'd need to get up and walk over to turn it on. And the colleague had been sitting the whole time without getting up. In the end, I quietly walked over and turned it off.
