One day, Chaim Yankel was trying to pull out of a parking place but to his horror, he hit the bumper of the car parked in front of him. To make matters worse, the incident was witnessed by a handful of people waiting for a bus.
So Chaim Yankel got out of his car, inspected the damage carefully, took out a pen and a piece of paper and wrote a note, which he then left under the wiper blade of the other car.
