As 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 car 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 insides. It is so special, so wonderful,
that he can reveal it only to his family, only when he returns home, ony
at the end of the day.
