The father said: you gossip about a man that you didn’t know, and endanger his life and his reputation without knowing? Yes, that was wrong,
go to your house, take a pillow do the roof, and stab it with a knife, than come back to me tomorrow said the father.
The woman went to her house, took a pillow to the roof and stabbed it with a knife as instructed, and then come back to the father.
The father ask her: what happened when you stabbed the pillow?
she said: feathers came out of it. Feathers everywhere, going with the wind.
And the father said: go back to your house and pick every feather that went out.
The woman said it was impossible.
So the father said: that is exactly what you have done with your gossip, your words have gone with the wind, and now no one knows where they go.
