One day two men met in the middle of a bridge over a stream. The bridge was narrow and only one person could cross the bridge at a time. Both of them felt that it was the other man’s duty to make way. They had a serious argument. They attacked each other, fell in to the water and were drowned.
Some days later two other man met on the bridge in the same way. Both were quit peaceful. One of them sat down on the bridge and let the other man step over him and go on his way. Thus oth of them crossed the bridge safely.
