Do not judge your friend until you stand in his place

Friends are flowers in the garden of life

These can never be true friends: Hope, dice, a prostitute, a robber, a cheat, a goldsmith, a monkey, a doctor, a distiller.

Speak well of your friend, of your enemy say nothing.

If you're going to live by the river, make friends with the crocodile

A friend to everybody is a friend to nobody
