A favor given to man is appreciated by none.

Some suggestions for you :
He who steals in order to give to god can only get advice from the devil.
There's nothing worse for an intelligent person than to put a fool beside him.
Renounce a friend who covers you with his wings and destroys you with his beak.
Many things are too bad to be blessed, and too good to be cursed.
Pretend you're in great danger, and you'll find out if you have any friends.
