I do not want a friend who smiles when I smile, who weeps when I weep; for my shadow in the pool can do better than that.

Silence is a true friend who never betrays.

There are three sorts of pleasures which are advantageous, and three which are injurious. Finding pleasure in the discriminating study of ceremonies and music, finding pleasure in discussing the good points in the conduct of others, and finding pleasure in having many wise friends, these are advantageous. But finding pleasure in profligate enjoyments, finding pleasure in idle gadding about, and finding pleasure in feasting, these are injurious.

Silence is the true friend that never betrays.

Have no friends not equal to yourself.
