I recently got stuck with Aesop's Fables and I liked this one!
A snail found a mirror and when she saw how brightly he shone, she fell in love with him. She quickly climbed up onto the mirror's round surface and began to lick him. The snail clearly was no good for the mirror and only besmirched his lustrous radiance with filth and slime. A monkey then found the mirror after it had been dirtied by the snail, and remarked, 'That's what happens when you let someone like that walk all over you!'
