Aesop's Fables - Very Short Story

A GREAT CITY was besieged, and its inhabitants were called together to consider the best means of protecting it from the enemy. A Bricklayer earnestly recommended bricks as affording the best material for an effective resistance. A Carpenter, with equal enthusiasm, proposed timber as a preferable method of defense. Upon which a Currier stood up and said, "Sirs, I differ from you altogether: there is no material for resistance equal to a covering of hides; and nothing so good as leather."

Moral:

Every man for himself
