Fortunate men are admonished by the adventures and similes of those who have preceded them, before those who follow them can use the event as a proverb, like thieves who shorten their hands, lest their hands be cut off.

 The bird does not go to the grain displayed 
 When it beholds another fowl in the trap. 
 Take advice by the misfortunes of others 
 That others may not take advice from thee.
