Be mild to the mild and harsh to the harsh 
And tough to the tough to stay fit. 
 
Be not a liar to the liar,  
A cheat to the cheat, a thief to the thief 
And better avoid such men. 
 
Be a miser to the greedy,  
A possessive to the selfish 
To discourage their habit. 
 
Be good to the bad 
Is a cowardly act.
