Good friends are hard to find, harder to leave, and impossible to forget.
It is one of the blessings of old friends that you can afford to be stupid with them.
Only your real friends will tell you when your face is dirty.
He who has a thousand friends has not a friend to spare, And he who has one enemy will meet him everywhere.
Abuse a man unjustly, and you will make friends for him.
Without friends no one would choose to live, though he had all other goods.
Our friends show us what we can do our enemies teach us what we must do.
Books are the quietest and most constant of friends they are the most accessible and wisest of counsellors, and the most patient of teachers.
