From the Tao ….
One day a man found that his axe was missing, and suspected his neighbour’s son of having taken it. Observing the youth walking around, the man was convinced that his was the walk of a thief. The youth looked like a thief and talked like a thief; everything he did pointed to his having stolen the axe.
Then one day the man happened to find his missing axe. After that, he noticed his neighbor’s son wasn’t behaving like a thief anymore.
