"That laundry is not very clean; she doesn't know how to wash correctly. Perhaps she needs better laundry soap."
Her husband looks on, remaining silent. Every time her neighbour hangs her wash to dry, the young woman makes the same comments.
A month later, the woman is surprised to see a nice clean wash on the line and says to her husband:
"Look, she's finally learned how to wash correctly. I wonder who taught her this? "
And so it is with life...
What we see when watching others depends on the clarity of the window through which we look."
