[A] camel and his owner … were traveling across the desert sand dunes when a wind storm came up. The traveler quickly set up his tent and moved in, closing the flaps to protect himself from the cutting, grinding sands of the raging storm. The camel was of course left outside, and as the violent wind hurled the sand against his body and into his eyes and nostrils he found it unbearable and finally begged for entrance into the tent.

“‘There is room only for myself,’ said the traveler.

“‘But may I just get my nose in so I can breathe air not filled with sand?’ asked the camel.

“‘Well, perhaps you could do that,’ replied the traveler, and he opened the flap ever so little and the long nose of the camel entered. How comfortable the camel was now! But soon the camel became weary of the smarting sand on his eyes and ears … :

“‘The wind-driven sand is like a rasp on my head. Could I put just my head in?’
