A mother mouse and her three children crept out of their hole into the kitchen and began feasting on some delicious bits of food. Suddenly, out of the corner of her eye, Mother Mouse saw a cat slinking toward them.

The cat was between the mice and their hole. The mother mouse puffed up her lungs and went, "Woof! Woof!" The cat turned tail and ran. With that, the mother quickly led her children back to safety in their hole.

When they were settled, and breathing normally, Mother Mouse said to her children, "Now, what's the lesson from that experience?"

"We don't know," the baby mice squeaked.

"It is this," said Mother Mouse. "It's always good to know a second language."
