英语寓言故事-The Fishermen

SOME FISHERMEN were out trawling their nets.
Perceiving them to
be very heavy, they danced about for joy and supposed that they
had taken a large catch.
When they had dragged the nets to the
shore they found but few fish:
the nets were full of sand and
stones, and the men were beyond measure cast downso much at the
disappointment which had befallen them, but because they had
formed such very different expectations.
One of their company,
an old man, said, "Let us cease lamenting, my mates, for, as it
seems to me, sorrow is always the twin sister of joy; and it was
only to be looked for that we, who just now were over-rejoiced,
should next have something to make us sad."
