     Once upon a time, there was a little weasel (鼬鼠). His name was Horace. Unlike all the other

weasels, Horace was very bookish.

     He had a copy of The Little Prince that he had found out behind a chicken house. The third chapter

of the book was missing and the back cover was broken, but it was the only book he had, and he loved

it. While all the other weasels spent their time playing, Horace would read instead. This made the other

weasels surprised, but they let it go by.

     Then, one day, the Earth was invaded (入侵) by space aliens. These aliens were a group of giant

librarians. Because they were librarians, they had of course done their research before they began their

invasion.     

     Meanwhile, the librarians went out to make contact with the species with whom they felt the most

affinity (密切关系). They had hoped that they could find the great works of weasel literature, but they

found that this was not so. The giant weasel librarian aliens were very disappointed. "Is there no weasel

at all who loves books as we do?" (Naturally, they had learned to speak the weasel language.) "No,"

said the weasels.

     At last, they came to the town where Horace lived. Here the weasels said "Yes!" They found Horace

and placed him in their libraries, where at last he got a complete edition of The Little Prince. He read it

every day for the rest of his life.
