An old Lion lives in the forest. He is too old to hunt. How can he get his food? He thinks of a clever plan. He puts a note on his door. It says: "I am old and hungry. Please come and visit me before I die." So all the animals go to see the old lion. First a sheep comes to visit him. Then a cow, then a rabbit, then a deer, then a donkey, and last of all a young goat. After each visitor, the lion feels better. He licks his lips and smiles. Now the fox comes to visit him. The lion asks the fox to come into his house. But the fox doesn't come in. She is standing near his house. The fox says: "No, thank you. I don't want to come in." "Why don't you want to come in?" asks the old lion. The fox looks at the footprints all around the lion's house. Then she says to the lion: "Look at these footprints. They all lead to your house, but they don't lead out of your house. When all your visitors come out, then I will come in to visit you!"
