“By seeing the worst, which late on hopes depended. To mourn a mischief that is past and gone Is the next way to draw new mischief on. What cannot be preserved when fortune takes, Patience her injury a mockery makes. The robb'd that smiles steals something from the thief; He robs himself that spends a bootless grief.
BRABANTIO. So let the Turk of Cyprus us beguile, We lose it not so long as we can smile; He bears the sentence well, that nothing bears But the free comfort which from thence he hears; But he bears both the sentence and the sorrow” source
