It was dreadful in the trenches during World War First. Millions of soldiers waited in anticipation of death or killing. There was a kind of no man’s land between the trenches of the opposing armies. Across a slowly smoldering front between the German and the allied troops in Europe, a German soldier was reputed for his stealthy prowl. He would stalk the enemy fleas like a predatory lizard across the buffer zone and preyed upon some lone soldier, disarmed him and forced him to crawl back to his side. He had completed a dozen such successful missions. On one such mission in the dark of night, he overpowered an allied soldier. The allied soldier was eating bread. The initial impulse is to resist your enemy. Had he done so, his fate would have been like others who had been kidnapped by the German soldier. As the German soldier started to disarm him, the captive allied troop offered his bread to the enemy. If you offer something to someone, you put that person in an obligation, almost indebted to you. You feel like paying back. This law applies to all cultures and is one of the basic laws of human society. The German soldier found himself detained by the subtle chains of this law. He spared the soldier and returned empty ended.
