A man who lost his axe suspected his neighbour's son of stealing it. To him, as he observed the boy, the way the lad walked, the expression on his face, the manner of his speech - in fact everything about his appearance and behaviour betrayed that he had stolen the axe.
Not long afterwards the man found his axe while digging in his cellar. When he saw his neighbour's son again, nothing about the boy's behaviour nor appearance seemed to suggest that he had stolen the axe.
