Never speak ill of an absent friend.
It is wretched business to be digging a well just as thirst is mastering you.
To love is human, it is also human to forgive.
If you do anything well, gratitude is lighter than a feather; if you give offense in anything, people's wrath is as heavy as lead.
No guest is so welcome in a friend's house that he will not become a nuisance after three days.
Consider the little mouse, how sagacious an animal it is which never entrusts its life to one hole only.
