Long long ago, a cat and a mouse were good friends. They lived a happy life in the same house. One day they went to a store and bought a big cake. They put it under a tree for winter.
A few days later, the mouse wanted to eat the cake. He told the cat he had to go to a baby's birthday party, and then left. The mouse ate half of the cake and returned home. When the cat asked him what the baby's name was, the mouse said, "Half gone".
After a few days, the mouse wanted to eat the cake again. He told the cat he had to go to another baby's birthday party. He finished the other half and told the cat the baby's name was "All gone".
When winter came, the cat went to the tree to get the cake. But he found nothing. From then on, the cat and the mouse were not friends any more.
