The Day of Ahmed's SecretAs young Ahmed delivers butane gas to customers all over the city of Cairo, he thinks, I have a secret. All day long, as he maneuvers his donkey cart through streets crowded with cars and camels, down alleys filled with merchants' stalls, and past buildings a thousand years old, Ahmed keeps his secret safe inside. It is so special, so wonderful, that he can reveal it only to his family, only when he returns home, only at the end of the day.
