Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE CHARCOAL BURNER AND THE FULLER
A charcoal burner who lived in a certain house decided it would be a good idea
to live together with a fuller who had moved in next door. But the fuller told
him, 'How on earth would I be able to carry on with my work? I am afraid that
whatever I washed white, you would cover with soot!'
The story shows that opposites are utterly incompatible.
