A Charcoal¹-burner carried on his trade in his own house. One day he met a friend, a Fuller, and entreated² him to come and live with him, saying that they should be far better neighbors, and that their housekeeping expenses would be lessened³. The Fuller replied: "The arrangement is impossible as far as I am concerned, for whatever I should whiten, you would immediately blacken again with your charcoal."

Like will draw like.
