We must consider what is the time for singing, what the time for play, and in whose presence: what will be unsuited to the occasion; whether our companions are to despise us, or we to despise ourselves: when to jest, and whom to mock at: and on what occasion to be conciliatory and to whom: in a word, how one ought to maintain one’s character in society. Wherever you swerve from any of these principles, you suffer loss at once; not loss from without, but issuing from the very act itself.
