To accept a favor is to sell one's freedom. -Beneficium accipere libertatem est vendere
Better use medicines at the outset than at the last moment.
Give your friend cause to blush, and you will be likely to lose him.
It is folly to censure him whom all the world adores.
He knows not when to be silent who knows not when to speak.
A gift in season is a double favor to the needy.
