A traveller was staying in an Egyptian village. One day, she held up her camera to take pictures of the children. Suddenly the young ones began to shout at her. The traveller's face turned red and she apologized to the head for what she was doing, and told him she had forgotten that people in some places believed a person would lose his soul(灵魂) if his picture was taken. She explained to him the operation of a camera for a long time. Several times the head tried to say something, but he couldn't.
