Starting with cleaning the windows

In the morning, as soon as he gets to the kitchen for coffee, the husband finds his wife astonished before the window.

—What a filthy neighbor! How can she be so slovenly? Look at the sheets on her clothesline, they are so dirty! — she says.

And it happens again, the next day. And the next.

—My love, have you seen how filthy the neighbor is? The sheets are all stained, what dirt! — she insists, disapprovingly.

And the band plays this way time after time.

Until the husband one day takes a cloth and cleans their own house’s windows. And those sheets come clean at once.
