I waited at the passage point of a small factory. End of working day. Employees and employees leave their workplaces and go home. Suddenly there was rain. Two middle-aged women decided to wait for the rain in the lobby, at the exit. They talked, the rain was over, and they all talked about something. I go out into the hallway, open the electric shield, loudly click on the free switch and say, “I have turned off the rain, go home.” The ladies looked out the window, where the rain stopped, and then stared at me. Those three seconds, while they thought, were invaluable. They laughed when they came out of the door.
