Never speak ill of an absent friend.
What you lend is lost; when you ask for it back, you may find a friend made an enemy by your kindness. If you begin to press him further, you have the choice of two things - either to lose your loan or lose your friend.
That which you know, know not; and that which you see, see not.
I seek the utmost pleasure and the least pain.
To waste one's breath; to pump into a sieve.
A man with courage has every blessing.
