My favorite story is The Fox and the Crow.
The fox wanted to get the meat in the crow's
mouth.So he said a lot of beautiful words to the
crow.The crow was so happy that he opened his
mouth to sing a song.But as soon as he opened his
mouth,the meat fell onto the ground and the fox got
it.
I think the story is interesting and meaningful.
It reminds me that we should never believe the
person who wants to cheat us.
