Fable 76 - The House-ferret and Aphrodite

A house –ferret, having fallen in love with a handsome young man, begged Aphrodite, goddess of love, to change her into a human girl.
The goddess took pity on this passion and changed her into a gracious young girl. The young man, when he saw her, fell in love with her
and led her to his home. As they rested in the nuptial chamber, Aphrodite, wanting to see if in changing body the house-ferret had also
changed in character, released a mouse I the middle of the room. The house-ferret, forgetting her present condition, leapt up from the
bed and chased the mouse in order to eat it. Then the indignant goddess changer her back to her former state.

Bad people who change their appearance do not change their character.
