My elder sister is an airhostess (飞机服务员). Yesterday morning my sister was at the back of the plane.
She was going to take food and drinks to the passengers. A little old woman, who took on the plane for the
first time, came up to her and said, "Could you tell me where the Ladies' Room is?"
     "Certainly, Madam," answered my sister. "It is right at the other end of the plane in the front." The old
woman went too far. She walked all the way to the front of the plane, opened the door in front of her and
saw the captain (机长) and his workmates in the small room. They were all busy with their work and didn't
see her. She went out again and came back to my sister. "Oh, did you find it?" asked my sister. "Yes, I did,"
said the little old woman."But there were four men in the Ladies' Room watching TV!"
