Classic Poem

A merchant, having suffered loss of a thousand dinars, enjoined his son not to reveal it to anyone. The boy said: ‘It is thy order and I shall not tell it but thou must inform me of the utility of this proceeding and of the propriety of concealment.’ He replied: ‘For fear the misfortune would be double; namely, the loss of the money and, secondly, the joy of neighbours at our loss.’

Reveal not thy grief to enemies
Because they will say ‘La haul’ but rejoice.
