Read the excerpt from chapter 7 of Night. One day when we had come to a stop, a worker took a piece of bread out of his bag and threw it into a wagon. There was a stampede. Dozens of starving men fought desperately over a few crumbs. The worker watched the spectacle with great interest.

Years later, I witnessed a similar spectacle in Aden. Our ship's passengers amused themselves by throwing coins to the "natives,” who dove to retrieve them. An elegant Parisian lady took great pleasure in this game. When I noticed two children desperately fighting in the water, one trying to strangle the other, I implored the lady:

"Please, don’t throw any more coins!”

"Why not?” said she. "I like to give charity . . .”
