The Boasting Traveler

A man who had traveled in foreign
lands boasted very much, on returning to his own country, of the many wonderful
and heroic deeds he had performed in the different places he had visited.

Among other things, he said that when
he was at Rhodes he had leaped to such a distance that no man of his day could
leap anywhere near him as to that, in Rhodes
there were many persons

who saw how he did it and whom he
could call as witnesses.

One of the people who were standing
by interrupted him, saying: "Now,
my good man, if this be all true there
is no need of witnesses. Suppose this to
be Rhodes, and leap for us." The man felt
ashamed and confused as he certainly couldn’t do that.

And the people around said: “He who
does a thing well does not need to boast”.
