Sincerity must be used in moderation, even with our most intimate friends. To be too frank is to put into an opinion what may be simply ill temper; it is to risk losing a friend because of a poorly digested roast, a headache, a thunderstorm.

André Maurois (1885-1967) French author [b. Émile Salomon Wilhelm Herzog]

Conversation, “Sincerity” (1930)
