A town mouse and a country mouse were friends.
One day, the town mouse visited the country mouse. The country mouse prepared lots
of food he grew, but the town mouse didn't like it.
After eating, the town mouse asked the country
mouse to come to his town. The town mouse showed the visitor into his room which
had a lot of nice food. The country mouse had never seen anything like that and
sat down to enjoy the food. But right before they had eaten, the door opened and
someone came in. The two mice had to hide themselves in a narrow hole. After a while,
when it was quiet again, they came out. But someone else came in, and they hid again.
"Goodbye," said the country mouse,
"I'm leaving. You have a lot of nice food to eat. I can see, but there is so
much danger." In the end, the country mouse decided to go back home and he
no longer envied town at all.
