One day a snake lay at the foot of a hill. A sun was warm         
and he soon went to asleep. Suddenly a big stone fell down the hill. 
It fell on the snake. He woke up and find he could not move,          
for the stone was very light. Just at that moment a rabbit came up. 
“Mr. Rabbit,” said the snake, “the stone hurts me bad.             
Move it off me, please, and I shall give a gift for you.” 
The rabbit was very kind. He did not like to see someone in trouble.  
So he tried push the stone. He pushed and pushed until he moved     
the stone off the snake. The snake was free, and the rabbit got tired.
But on that time, the snake said, “I'm dying of hunger.    
I want to eat up you.”
