Once upon a time, on a farm there was a thirsty cat and a tortoise. The thirsty cat was going to die. The tortoise knew that the cat was going to die. He said, "Go to the pond! but first follow me to the pond." The tortoise found the pond and he told the cat that, "I found the pound." So he told the cat to come and look. The cat ran as fast as he could to the pond to get water to drink. Then, after they had enough water, they were good friends forever after. 
We need to help each other.
