Once upon a time, there was a gray cat. The gray cat was very hungry. So, the cat went to find food to eat. The cat walked and walked to look for something to feed on.
The gray cat found a prune on the ground. The cat thought, "I will eat the prune to not be hungry anymore." The cat ate the prune. The cat felt good after eating it.
But then, the cat felt sick. The prune was bad. The cat's tummy hurt. The cat lay down and did not get up again. The gray cat should not have eaten the bad prune.
