A young couple moves into a new neighbourhood. The next morning, while they are eating breakfast, the young woman sees the neighbour hang up the wash outside.
‘That laundry is not very clean,’ she said, ‘she doesn’t know how to wash correctly. Perhaps she needs different washing powder.’
The husband looked on, but remained silent. Every time her neighbour would hang out the wash, the young woman would make the same comment. About one month later, the woman was surprised to see a nice clean wash on the line and said to her husband, ‘Look! She has learned how to wash correctly. I wonder who taught her.’
Her husband said, ‘I got up early this morning and cleaned our windows.’
And so it is with life: What we see while watching others depends on the purity of the window through which we look.
