Walls have ears, bottle have mouths.

Virtue will have a good reward; vice will have an veil recompense.

Unpleasant advice is a good medicine.

Two heads are better than one.

Two blacks do not make a white.

Truth never hurts the teller.

True words hurt.

To know one's self is true progress.

To err is human, to forgive divine.

To be rich and not haughty; to be poor and not grumble.
