So He lived alone, and was in his apartment clean without much effort. She lived in the neighboring apartment, and it was just as clean with her, and she spent about as little effort on it. And then they started living together andining cleanliness without titanic efforts became simply impossible... magic, no other way :)

Now take care of your hands.
He and she lived. They came home mostly to sleep, smelled all day, ate at work, spent the weekend with friends outside. not stumbled. And then they became a couple and want to spend free time at home, together. The house becomes dirty and needs to be cleaned. And then there are cats and they do not clean themselves. It takes more time to clean up. This is what the man you suspect in witchcraft has written about.
Probably the reason for such statements, as in medieval illiteracy.
